* add test with MAX_CONCURRENT_STREAMS
* don't transparently retry if we're already committed
* fix test to not reuse byte buffers
* clang-format

* Move XdsChannelCreds to CoreConfiguration

* Change back to returning a RefCountedPtr.

Partially collapse `event_engine_factory.cc` into `event_engine.cc`. Add a
new function `DefaultEventEngineFactory` which is used to set a default
event engine factory at link time, separate from the factory that can be
set at run time. Implemenet this function in
`default_event_engine_factory.cc`.
This allows alternative default event engine factories to be implemented
without requiring the duplication of the implementations of
`SetDefaultEventEngineFactory`, `CreateEventEngine`, and
`GetDefaultEventEngine`.
* HTTP2: Add GrpcNetworkStreamState metadata for calls that are not sent on wire and for those that are not seen by server
* Generate projects
* clang-tidy
* Fix test
* clang-tidy
* Add a negative test
* Fix for windows
This avoids having to do a cherry-pick import, and is harmless since
there are no dependencies yet on the EventEngine. This test will be
re-enabled shortly after both the import and related changes are
finished.
