gRPC shutdown may happen asynchronously with `work_serializer_dispatch`, so wait briefly until shutdown completes in the child's post-fork.

All TraceFlags are now configured in `src/core/lib/debug/trace_flags.yaml`. The format is:
```
my_flag:
default: false # the default value; default=false
description: Some Description
debug_only: false # debug_only flags only work in debug builds; default=false
internal: false # internal flags will not show up in documentation; default=false
```
To regenerate the trace flag source code, run `tools/codegen/core/gen_trace_flags.py` (requires mako). This script is also run when sanity checking.
This PR also adds two new features:
### Glob-based flag configuration
Trace flag configuration now supports `?` (single wildcard character) and `*` (one or more wildcard characters). For example, using `GRPC_TRACE='event_engine*'` will enable all flags that match that glob. It expands to:
* event_engine
* event_engine_client_channel_resolver
* event_engine_dns
* event_engine_endpoint
* event_engine_endpoint_data
* event_engine_poller
### A cleaner trace-logging macro in abseil logging format
If your goal is only to add log statements when the `fault_injection_filter` trace flag is enabled, you can use the macro:
```
GRPC_TRACE_LOG(fault_injection, INFO) << "Filtered:" << 42;
```
When the trace flag is enabled, the the log will show something like this:
```
I0000 00:00:1715733657.430042 16 file.cc:174] Filtered:42
```
----
Note: just like with the gpr_log to abseil logging conversion, the pre-existing trace logging usages can be replaced with the new tracing macro across multiple PRs.

The following attributes were added but never programmatically accessed, and I've moved them into the status messages themselves, which is another step toward #22883:
- kErrorNo

Add registered method change to sync stack server.
## Note
* We're keeping both generic and registered handler in generated stubs (`*_pb2_grpc.py`) because registered method flow is not implemented in aysncio yet, since the stub is used for both sync and asyncio, we can't remove generic method flow until we fully implement the registered method flow in asyncio.

[grpc][Gpr_To_Absl_Logging] Migrating from gpr to absl logging GPR_ASSERT
Replacing GPR_ASSERT with absl CHECK.
These changes have been made using string replacement and regex.
Will not be replacing all instances of CHECK with CHECK_EQ , CHECK_NE etc because there are too many callsites. Only ones which are doable using very simple regex with least chance of failure will be replaced.
Given that we have 5000+ instances of GPR_ASSERT to edit, Doing it manually is too much work for both the author and reviewer.

Also begin to eliminate `CallContext` in favor of just exposing `Call` - ultimately there's not really a need to introduce two types here, so I'm going to wind that idea back over a few PRs.

### NOTE
* We shouldn't merge this PR until GCP cloud functions drops support for Python 3.7 ([Currently scheduled for GCF](https://cloud.google.com/functions/docs/runtime-support#python))
As part of supporting Python 3.12, we're now officially drop support for Python 3.7.
This PR:
* Changed supported Python version from 3.7 to 3.8 in README.
* Replaced distribution test image from `debian:buster` to `debian:bullseye` since the default Python version in buster is 3.7.
