This PR implements a c-ares based DNS resolver for EventEngine with the
reference from the original
[grpc_ares_wrapper.h](../blob/master/src/core/ext/filters/client_channel/resolver/dns/c_ares/grpc_ares_wrapper.h).
The PosixEventEngine DNSResolver is implemented on top of that. Tests
which use the client channel resolver API
([resolver.h](../blob/master/src/core/lib/resolver/resolver.h#L54)) are
ported, namely the
[resolver_component_test.cc](../blob/master/test/cpp/naming/resolver_component_test.cc)
and the
[cancel_ares_query_test.cc](../blob/master/test/cpp/naming/cancel_ares_query_test.cc).
The WindowsEventEngine DNSResolver will use the same EventEngine's
grpc_ares_wrapper and will be worked on next.
The
[resolve_address_test.cc](https://github.com/grpc/grpc/blob/master/test/core/iomgr/resolve_address_test.cc)
which uses the iomgr
[DNSResolver](../blob/master/src/core/lib/iomgr/resolve_address.h#L44)
API has been ported to EventEngine's dns_test.cc. That leaves only 2
tests which use iomgr's API, notably the
[dns_resolver_cooldown_test.cc](../blob/master/test/core/client_channel/resolvers/dns_resolver_cooldown_test.cc)
and the
[goaway_server_test.cc](../blob/master/test/core/end2end/goaway_server_test.cc)
which probably need to be restructured to use EventEngine DNSResolver
(for one thing they override the original grpc_ares_wrapper's free
functions). I will try to tackle these in the next step.

This reverts the following PRs: #32692#33087#33093#33427#33568
These changes seem to have introduced some flaky crashes. Reverting
while I investigate.
In preparation for implementing the promise based version, separate out
the legacy call data from the filter.
There are two commits here, each representing one phase of this code
movement:
66676d398c moves `class RetryFilter` into
the header and the vtable name into that class, as this will be shared
code between the implementations
4c84f115ad then moves `class
RetryFilter::CallData` into `class RetryFilterLegacyCallData`, and moves
*that* into its own file
Doing so makes me less confused as to what I'm editing going forward.
No functionality should be affected.

More work on the dualstack backend design:
- Change ring_hash policy to delegate to pick_first instead of creating
subchannels directly.
- Note that, as mentioned in the WIP gRFC, because we lazily create the
pick_first child policies, so there's no need to swap over to a new list
as an atomic whole. As a result, we don't use the endpoint_list library
in this policy; instead, we just update a map in-place.
- Remove now-unused subchannel_list library.
More work on the dualstack backend design:
- Change round_robin to delegate to pick_first instead of creating
subchannels directly.
- Change pick_first such that when it is the child of a petiole policy,
it will unconditionally start a health watch.
- Change the client-side health checking code such that if client-side
health checking is not enabled, it will return the subchannel's raw
connectivity state.
- As part of this, we introduce a new endpoint_list library to be used
by petiole policies, which is intended to replace the existing
subchannel_list library. The only policy that will still directly
interact with subchannels is pick_first, so the relevant parts of the
subchannel_list functionality have been copied directly into that
policy. The subchannel_list library will be removed after all petiole
policies are updated to delegate to pick_first.
The address attribute interface was intended to provide a mechanism to
pass attributes separately from channel args, for values that do not
affect subchannel behavior and therefore do not need to be present in
the subchannel key, which does include channel args. However, the
mechanism as currently designed is fairly clunky and is probably not the
direction we will want to go in the long term.
Eventually, we will want some mechanism for registering channel args,
which would provide a cleaner way to indicate that a given channel arg
should not be used in the subchannel key, so that we don't need a
completely different mechanism. For now, this PR is just doing an
interim step, which is to establish a special channel arg key prefix to
indicate that an arg is not needed in the subchannel key.

The approach of doing a recursive function call to expand the if checks
for known metadata names was tripping up an optimization clang has to
collapse that if/then tree into an optimized tree search over the set of
known strings. By unrolling that loop (with a code generator) we start
to present a pattern that clang *can* recognize, and hopefully get some
more stable and faster code generation as a benefit.

This is another attempt to add support for vsock in grpc since previous
PRs(#24551, #21745) all closed without merging.
The VSOCK address family facilitates communication between
virtual machines and the host they are running on.
This patch will introduce new scheme: [vsock:cid:port] to
support VSOCK address family.
Fixes#32738.

Most of these data structures need to scale a bit like per-cpu, but not
entirely. We can have more than one cpu hit the same instance in most
cases, and probably want to cap out before the hundreds of shards some
platforms have.

Upgrade apple platform deployment_target versions to fix the cocoapods
push of BoringSSL-GRPC about the following error:
```
ld: file not found: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/arc/libarclite_macosx.a
clang: error: linker command failed with exit code 1 (use -v to see invocation)
```
ref: https://developer.apple.com/forums/thread/725300
This also aligns with the versions required by
[protobuf](https://github.com/protocolbuffers/protobuf/pull/10652)
```
ios.deployment_target = '10.0'
osx.deployment_target = '10.12'
tvos.deployment_target = '12.0'
watchos.deployment_target = '6.0'
```
This test mode tries to create threads wherever it legally can to
maximize the chances of TSAN finding errors in our codebase.

The logger uses `absl::FPrintF` to write to stdout. After reading a
number of sources online, I got the impression that `std::fwrite` which
is used by `absl::FPrintF` is atomic so there is no locking required
here.

This makes the JSON API visible as part of the C-core API, but in the
`experimental` namespace. It will be used as part of various
experimental APIs that we will be introducing in the near future, such
as the audit logging API.
This PR implements a work-stealing thread pool for use inside
EventEngine implementations. Because of historical risks here, I've
guarded the new implementation behind an experiment flag:
`GRPC_EXPERIMENTS=work_stealing`. Current default behavior is the
original thread pool implementation.
Benchmarks look very promising:
```
bazel test \
--test_timeout=300 \
--config=opt -c opt \
--test_output=streamed \
--test_arg='--benchmark_format=csv' \
--test_arg='--benchmark_min_time=0.15' \
--test_arg='--benchmark_filter=_FanOut' \
--test_arg='--benchmark_repetitions=15' \
--test_arg='--benchmark_report_aggregates_only=true' \

Reverts grpc/grpc#32924. This breaks the build again, unfortunately.
From `test/core/event_engine/cf:cf_engine_test`:
```
error: module .../grpc/test/core/event_engine/cf:cf_engine_test does not depend on a module exporting 'grpc/support/port_platform.h'
```
@sampajano I recommend looking into CI tests to catch iOS problems
before merging. We can enable EventEngine experiments in the CI
generally once this PR lands, but this broken test is not one of those
experiments. A normal build should have caught this.

Makes some awkward fixes to compression filter, call, connected channel
to hold the semantics we have upheld now in tests.
Once the fixes described here
https://github.com/grpc/grpc/blob/master/src/core/lib/channel/connected_channel.cc#L636
are in this gets a lot less ad-hoc, but that's likely going to be
post-landing promises client & server side.
We specifically need special handling for server side cancellation in
response to reads wrt the inproc transport - which doesn't track
cancellation thoroughly enough itself.

Third-party loggers will be added in subsequent PRs once the logger
factory APIs are available to validate the configs here.
This registry is used in `xds_http_rbac_filter.cc` to generate service
config json.
This paves the way for making pick_first the universal leaf policy (see
#32692), which will be needed for the dualstack design. That change will
require changing pick_first to see both the raw connectivity state and
the health-checking connectivity state of a subchannel, so that we can
enable health checking when pick_first is used underneath round_robin
without actually changing the pick_first connectivity logic (currently,
pick_first always disables health checking). To make it possible to do
that, this PR moves the health checking code out of the subchannel and
into a separate API using the same data-watcher mechanism that was added
for ORCA OOB calls.
The PR also creates a separate BUILD target for:
- chttp2 context list
- iomgr buffer_list
- iomgr internal errqueue
This would allow the context list to be included as standalone
dependencies for EventEngine implementations.

The very non-trivial upgrade of third_party/protobuf to 22.x
This PR strives to be as small as possible and many changes that were
compatible with protobuf 21.x and didn't have to be merged atomically
with the upgrade were already merged.
Due to the complexity of the upgrade, this PR wasn't created
automatically by a tool, but manually. Subsequent upgraded of
third_party/protobuf with our OSS release script should work again once
this change is merged.
This is best reviewed commit-by-commit, I tried to group changes in
logical areas.
Notable changes:
- the upgrade of third_party/protobuf submodule, the bazel protobuf
dependency itself
- upgrade of UPB dependency to 22.x (in the past, we used to always
upgrade upb to "main", but upb now has release branch as well). UPB
needs to be upgraded atomically with protobuf since there's a de-facto
circular dependency (new protobuf depends on new upb, which depends on
new protobuf for codegen).
- some protobuf and upb bazel rules are now aliases, so `
extract_metadata_from_bazel_xml.py` and `gen_upb_api_from_bazel_xml.py`
had to be modified to be able to follow aliases and reach the actual
aliased targets.
- some protobuf public headers were renamed, so especially
`src/compiler` needed to be updated to use the new headers.
- protobuf and upb now both depend on utf8_range project, so since we
bundle upb with grpc in some languages, we now have to bundle utf8_range
as well (hence changes in build for python, PHP, objC, cmake etc).
- protoc now depends on absl and utf8_range (previously protobuf had
absl dependency, but not for the codegen part), so python's
make_grpcio_tools.py required partial rewrite to be able to handle those
dependencies in the grpcio_tools build.
- many updates and fixes required for C++ distribtests (currently they
all pass, but we'll probably need to follow up, make protobuf's and
grpc's handling of dependencies more aligned and revisit the
distribtests)
- bunch of other changes mostly due to overhaul of protobuf's and upb's
internal build layout.
TODOs:
- [DONE] make sure IWYU and clang_tidy_code pass
- create a list of followups (e.g. work to reenable the few tests I had
to disable and to remove workaround I had to use)
- [DONE in cl/523706129] figure out problem(s) with internal import

- `+trace` fixtures haven't run since 2016, so they're disabled for now

- all current fixtures define `FEATURE_MASK_SUPPORTS_AUTHORITY_HEADER`
and hence `authority_not_supported` has not been run in years - deleted
- bad_hostname similarly hasn't been triggered in a long while, so
deleted
- load_reporting_hook has never been enabled, so deleted
(f23fb4cf31/test/core/end2end/generate_tests.bzl (L145-L148))
- filter_latency & filter_status_code rely on global variables and so
don't convert particularly cleanly - and their value seems marginal, so
deleted

When using this internally, we noticed that it's impossible to use
custom_metadata.h without creating a dependency cycle between
:custom_metadata and :grpc_base.
A full build refactoring is too large right now, so merge that header
into :grpc_base for the time being.
Also, separate `SimpleSliceBasedMetadata` into its own file, so that it
can be reused in custom_metadata.h.
