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!

Otherwise when we fill in peer in `SetCommonEntryFields` it will be
empty/invalid.

The following bugs are fixed:
* Missing ExecCtx in event engine endpoints and listeners
* Ref counting issue with iomgr endpoint which causes crashes in
overloaded situations
The PR includes a test which triggers these bugs by simulating an
overloaded system.
With some delay, this is a PR for
https://github.com/grpc/grpc/issues/32564 (and previously
https://github.com/grpc/grpc/pull/31791).
I looked into adding a regular `py_test` for this change [as
suggested](https://github.com/grpc/grpc/pull/31791#issuecomment-1423245116)
but I am not aware of any effect that the presence of a .pyi stub file
would have at runtime and where some sort of type-checking in a .py
script would be affected. Stub files are only for use by type checkers &
IDE's. I mean, something like this would work:
```
import helloworld_pb2
py_file = helloworld_pb2.__file__
pyi_file = py_file + 'i’
self.assertTrue(os.path.exists(pyi_file))
```
But that seems really hacky to me. Instead I created a simple rule test
for `py_proto_library` with Bazel Skylib which tests the declared
outputs for an example `py_proto_library` target. Indirectly, this also
tests that the declared output files are actually generated. Please let
me know if this is sufficient.
- Switched from yapf to black
- Reconfigure isort for black
- Resolve black/pylint idiosyncrasies
Note: I used `--experimental-string-processing` because black was
producing "implicit string concatenation", similar to what described
here: https://github.com/psf/black/issues/1837. While currently this
feature is experimental, it will be enabled by default:
https://github.com/psf/black/issues/2188. After running black with the
new string processing so that the generated code merges these `"hello" "
world"` strings concatenations, then I removed
`--experimental-string-processing` for stability, and regenerated the
code again.
To the reviewer: don't even try to open "Files Changed" tab 😄 It's
better to review commit-by-commit, and ignore `run black and isort`.
The function grpc_rb_call_run_batch has many places that could raise
errors, including in child functions. Since a raised error will longjump
out of the function, it will cause memory leaks since the function
cannot perform any clean up. This commit fixes the issue by wrapping the
whole function in an rb_ensure, which will ensure that a cleanup
function is ran before the error is propagated upwards.

Revert "Revert "[core] Add support for vsock transport"
(https://github.com/grpc/grpc/pull/33276)"
This reverts commit
c5ade3011a.
And fix the issue which broke the python build.
@markdroth@drfloob please review this PR. Thank you very much.

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.

On endpoint shutdown, the `AsyncIOState` object was sometimes freed
before the last async read callback execution had run. This resulted in
callback handlers attempting to access a deleted `io_state_` object.
This PR removes the AsyncIOState dependency from the user callback
execution step, since only the callback and its status are needed at
that point.
Previous crashes were non-deterministic, but would reliably pop up once
on most runs of:
```
bazel test --cxxopt='/DEBUG=full' --config=windows_dbg --test_filter='CoreEnd2endTest*' \
--flaky_test_attempts=1 --cache_test_results=no \
--test_env=GRPC_VERBOSITY=debug --test_env=GRPC_TRACE=event_engine \
//test/core/end2end:core_end2end_tests@experiment=event_engine_client```

Reverts grpc/grpc#33223. Breaks internal build.
```
work_stealing_thread_pool.cc:180:27: error: format specifies type 'double' but the argument has type 'gpr_cycle_counter' (aka 'long') [-Werror,-Wformat]
```
We had an infinite recursion in our tracer parsing code... probably not
a biggy, but it was blocking the fuzzers so fixing.

This is a hack to get around an issue on Apple devices caused by the
PosixEventEngine's `poll` poller not supporting fork. This PR disables
the EventEngine poller entirely in Python builds. It will therefore
prevent the release of the EventEngine generally, and prevent any
testing of EventEngine integration with gRPC Python, until the `poll`
poller is fixed.
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.

For the details of the issue, please see #33157.
Add several paddings in struct grpc_comletion_quete to avoid the false
sharing.
I see performance improvement with the QPS tests.
cpp_protobuf_async_streaming_qps_unconstrained_1cq_insecure: ~2.9%
cpp_protobuf_async_unary_qps_unconstrained_1cq_insecure: ~7%

~5% flake introduced earlier this week, where the pool was not scaling
when draining work @ shutdown. Maintaining a busy thread count at
shutdown allows the lifeguard to notice when all threads are blocked,
and spawn new threads if necessary.
We were previously trying to adjust the initial guess flow control
window *and* the adjustment methodology, which created some problems.
The latter is more important for us to get in, so don't change the
former for now (we can do that later).

recv_initial_metadata_ in `RetryFilter::CallAttempt` is deleted before
it's accessed in
`ClientChannel::FilterBasedLoadBalancedCall::RecvTrailingMetadataReady`
- instead of accessing it, pull out peer string and keep a ref
- switch to json_object_loader for config parsing
- use `absl::string_view` instead of `const char*` for cert provider
names
- change cert provider registry to use a map instead of a vector
- remove unused mesh_ca cert provider factory
