Currently channel filter construction returns a `StatusOr<T>`, this change makes it return a `StatusOr<P<T>>` where P is `unique_ptr`, `OrphanablePtr`, `RefCountedPtr`, `DualRefCountedPtr`, etc (most of the code really doesn't need to know, so I'm choosing to leave the flexibility).
That smart pointer is then stored in the channel stack instance, and dereferenced when needed.
This means that channel filters no longer need to be movable (which is a nice simplification), and puts these level-1 filters on a similar memory management track as the level-2 filters we have planned.
(this change also converts client load reporting to v3 apis -- it's a bit accidentally picked up, but seems ok to pull through too)

The pick_first policy creates a list of subchannels for each resolver update and then iterates over the list, attempting to connect to each subchannel in turn, until one of them succeeds. However, once a subchannel does succeed, the policy unrefs the other subchannels but still retains a bunch of now-unnecessary state in the subchannel list itself. This wastes a bunch of memory, especially now that petiole policies are delegating to pick_first. This PR contains a new pick_first implementation that stops retaining that state, which significantly reduces per-channel memory.
There is one behavior change here, which is that if we have a connected subchannel and we get a resolver update that no longer includes that address, we now go IDLE instead of proactively trying to connect to the new addresses.

Forked from #35957
This PR refactors the credentials types to remove Secure and Insecure Channel and Call credentials types. We standardize on a `c_creds()` accessor method for all credentials types, which can now be treated uniformly. This notably removes special-case handling of insecure credentials.
The special code-paths for insecure creds are no longer necessary in the wake of #25586.

Instead, build a library and re-use that across compilations.
This still invokes a link step per target, and we'll want to deal with that at some point too, but at least this makes some progress to not being as wasteful with our compilation resources.

This removes two Executor::Run dependencies, and requires that all ServerCallbackCall implementations implement the new `RunAsync` method. There's one other known other implementation of ServerCallbackCall that will need to be updated.
We could also support an "inefficient" path that uses the default engine (not implemented here), for all subclasses that do not want to update. As far as anyone is aware, the ServerCallbackCall class was never intended to be subclassed externally.

Adding testing for `Size()` on `MeshLabelsIterable` as promised on https://github.com/grpc/grpc/pull/35371
This method doesn't get used the OTel C++ library at present so it was untested earlier, and bugs in its implementation were noticed later. To avoid that issue in the future, adding manual testing of this method.
Changes -
* Moved `MeshLabelsIterable` to the header to be able to test its Size method directly. Also had to move around some internals to be able to do so.
* Replaced `absl::variant<grpc_core::Slice, StructPb> metadata_` from decoding the metadata lazily to just decoding it in the constructor. I don't remember the original thinking behind this. Maybe I wanted the decoding to happen lazily, but there doesn't seem to be much gain from doing it lazily, we instead have to deal with the overhead of `variant`.

There were some failures in the Crl Directory related tests after https://github.com/grpc/grpc/pull/36031
This came down to https://github.com/grpc/grpc/pull/36031 adding some CRLs with bad qualities (invalid content/signatures, overriding issuer names) to the `test_creds/crl_data/crls` directory, which is used in the directory reloading tests. The tests began failing on some platforms because they were picking up these bad crls which were failing various checks, but the test was designed to assume that `test_creds/crl_data/crls` was a valid and good directory.
This PR moves the bad CRLs to their own directory to prevent this accidental mash-up of test data. It also adds debug logging to our custom verification stack.

Changes -
* Add CMake build support to `grpcpp_otel_plugin`. Currently, we are only supporting the `find_package CONFIG` method for depending on `opentelemetry-cpp`.
* Since, `grpcpp_otel_plugin` is an extension of gRPC, it will not be built by default. To enable building of this target, a new CMake option `gRPC_BUILD_GRPCPP_OTEL_PLUGIN` is being added.
* Also add `CMakeLists.txt` to the otel example.
The `otel_plugin_test` can also be built through cmake but, for the CI to work, there are some additional changes. Those will be made in an upcoming PR.

- `channel`: A virtual interface for a channel.
- `legacy_channel`: A channel implementation that supports the filter stack and call v2.
- `channel_create`: A standalone function to create a channel.
- `server_interface`: A base class with a few accessor methods used in surface/call.cc.
- `server`: The actual server implementation.
- `api_trace`, `call_tracer`, `server_call_tracer_filter`, `call_finalization`: These were split out of `grpc_base` to avoid various dependency problems.
- `compression`: This is a combination of the previously existing `compression_internal` target and the compression code that was part of `grpc_base`.
