PanCakes to the rescue!
We noticed that our 'sanity' test was going to fail, but we think we can fix that automatically, so we put together this PR to do just that!

This fixes rare failure under MSAN. This does not increate the test run time:
MSAN build:
```
//test/cpp/interop:backend_metrics_lb_policy_test@poller=poll PASSED in 59.2s
Stats over 5000 runs: max = 59.2s, min = 4.9s, avg = 6.5s, dev = 2.8s
```
Opt/no MSAN:
```
//test/cpp/interop:backend_metrics_lb_policy_test@poller=poll PASSED in 26.7s
Stats over 5000 runs: max = 26.7s, min = 4.9s, avg = 7.7s, dev = 2.8s
```
Closes#36308
Updates to `CallFilter` to get it ready for integration to `CallSpine`.
This is a bundle commit grabbed from my working branch so there's a few things rolled in here:
* PipeState picks up methods to close it cleanly and in error, and expands its Pull API to signify that error
* Add a `NextMessage` type that encapsulates one message pulled from a pipe (much like `Pipe::NextResult` - except that we know this is a message, and it's built on the `CallFilters` types)
* Add debug stringifiers to many CallFilters types, and better tracing
* Eliminate unused `CallFilters::PipePromise::Pull` type -- other variants are better for all cases
* Add support for filters having the signature `(Handle, Filter*) -> promise returning StatusOr<Handle>` - will support `ClientAuthFilter` in a future commit asynchronously mutating client initial metadata
Closes#36240
The build layout I chose in https://github.com/grpc/grpc/pull/36198 causes problems for Google's internal build systems. This change fixes things so that link order is correct - unfortunately at the cost of adding 90-some C++ compilations.
I've made a new .cc file that is as minimal as possible to reduce the cost of those compilations down as far as I can.

As per https://github.com/grpc/proposal/pull/419, the experimental optional label `grpc.lb.locality` is added to the follow per-call metrics -
* grpc.client.attempt.duration
* grpc.client.attempt.sent_total_compressed_message_size
* grpc.client.attempt.rcvd_total_compressed_message_size
Closes#36254
### 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.

[grpc][Gpr_To_Absl_Logging] Migrating from gpr to absl logging - GPR_ASSERT
Replacing GPR_ASSERT with absl CHECK
Will not be replacing CHECK with CHECK_EQ , CHECK_NE etc because there are too many callsites.
This could be done using Cider-V once these changes are submitted if we want to clean up later. Given that we have 4000+ instances of GPR_ASSERT to edit, Doing it manually is too much work for both the author and reviewer.

`Party` no longer needs to refer to `Arena`, and decoupling gives us a few more degrees of freedom in the design of a final `CallSpine`.
Also flesh out `LogStateChange` usage so that all state transitions are traced when that tracer is enabled.

Closes#36219
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.
Additionally: remove bm_pollset -- it was having some problems compiling, and we really don't need it anymore.
Closes#36197
Previously we wrote `DualRefCounted : public Orphanable`, but this is wrong: `Orphan`-ing is a private implementation detail to `DualRefCounted`, but a public interface to `Orphanable`.
This bug means that it's possible to write `OrphanablePtr<T>` when `T` is derived from `DualRefCounted`, leading to hard to diagnose bugs - especially when moving a previously `Orphanable` type to be `DualRefCounted`.
This change removes the inheritance from `Orphanable`, and instead adds an overridable method `Orphaned` that implementors of `DualRefCounted` can implement.
In this way we get:
* compiler errors if someone chooses to write `OrphanablePtr` for one of these types
* compiler errors if someone implements `Orphan()` instead of `Orphaned()` in the wrong place (or vice versa)
Closes#36194
Internally, use `std::vector` instead of `ChunkedVector` to hold extra metadatum.
I'm not totally convinced this is the right move, so it's going to be a try it and monitor for a month or so thing... I might roll back if performance is actually affected (but I think we'll see some wins and losses and overall about a wash).
Closes#36118
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.

Closes#36070
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`.

If party1 wakes party2 we'd prefer that party1 finishes all its activations before it wakes party2:
intuition: party1 might wake party2 for other things too, and being able to coalesce them all into one wakeup significantly helps performance.
Closes#36048
The function name was not very descriptive of its behavior, and there were no tests that made the behavior clear. The documentation had been wrong for some time, fixed in https://github.com/grpc/grpc/pull/36143. CC @nipilCloses#36144
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.

Earlier, the tests just had bazel support. With CMake support added in #36063
An error occurred
, we can also add CI CMake support for the tests. A major benefit of this is that we also get coverage for the various platforms that we test from our portability test suite.
