Builds upon #37765 to support arbitrary connection counts in the transport.
(note: at this point the number of connections is determined at connection establishment - future work will be autotuning this)

Increase timeout for Python basic tests on Windows
The tests are timing out on kokoro windows
We have added support for 3.13 python version but have not dropped support for any older version. hence overall number of tests have increased.

This pulls in a patch that increases the max iteration limit, which is useful for extra-small microbenchmarks.
Closes#38163

This PR addresses the frequent timeouts encountered by the Windows portability build-only test suite. Currently, the suite includes two tests: one using MSBuild and another using Ninja, both with MSVC 2022. To mitigate the timeout issue, this PR disables the MSBuild test while retaining the Ninja test.

Update the chaotic-good wire format with some learnings from the past year, and set up things for the next round of changes we'd like to make:
* Instead of a composite FRAGMENT frame, split out CLIENT_INITIAL_METADATA, CLIENT_END_OF_STREAM, MESSAGE, SERVER_INITIAL_METADATA, SERVER_TRAILING_METADATA as separate frame types - this eliminates a ton of complexity in the transport, and corresponds to how we used the wire format in practice anyway.
* Switch the frame payload for metadata, settings to be protobuf instead of HPACK - this eliminates the ordering requirements on interpreting these frames between streams, which I expect to open up some flexibility with head of line avoidance in the future. It's a heck of a lot easier to read and reason about the code. It's also easier to predict the size of the frame at encode time, which lets us treat metadata and payloads more uniformly in the protocol.
* Add a connection id field to our header, in preparation for allowing multiple data connections
* Allow payloads to be shipped on the control channel ('connection id 0') and use this for sending small messages

This change upgrades the sanity test to use Clang 19, including clang-format and clang-tidy. (It's a partial implementation of the changes proposed in #38038)
Key updates:
- Docker images now utilize Clang 19.
- Code has been reformatted using the updated clang-format.
- Resolved `readability-math-missing-parentheses` warnings raised by clang-tidy.
Note that the other part of the clang-19 upgrade, "using clang-19 for C++ test" will be done once opentelemetry-cpp fixes the clang-19 build error.

This might not be needed? (From https://github.com/grpc/grpc/issues/37976)
- Boringssl commit requiring -msse2: 56d3ad9d23 (diff-f628d148f94bbab9e22a1ad426ccd94311f1fb87bbe5cc533cb85aee18b07a20R248)
- gRPC change to add -msse2 https://github.com/grpc/grpc/pull/36089
---
Answer to the quesiton above is yes; The -msse2 option remains necessary for gRPC on i686 due to BoringSSL's requirements. However, the existing CMake condition for this option was too broad, potentially including ARM architectures where SSE2 isn't supported, leading to compilation errors. I've refined the condition to specifically target 32-bit x86 architectures.
Furthermore, to ensure accurate architecture detection within our dockerized tests, I've configured x86 tests to utilize the linux32 command. This ensures that uname -a correctly reports i686, allowing gRPC's CMake to identify the architecture and apply the -msse2 option as needed.
It's important to note that RBE overrides the default entrypoint, so RBE-based tests must explicitly invoke linux32 even if the Docker image already has it set.

[PH2][NewFile][ClassStructure][Important] Add client and server class
1. New classes Http2ServerTransport and Http2ClientTransport
2. Similar to the classes in [Chaotic Good Client Transport](https://github.com/grpc/grpc/blob/master/src/core/ext/transport/chaotic_good/client_transport.h) and [Chaotic Good Server Transport](https://github.com/grpc/grpc/blob/master/src/core/ext/transport/chaotic_good/server_transport.h)
3. Added new Test files. For now, the 2 new tests just call the constructor of Http2ServerTransport and Http2ClientTransport.
Tested locally using
```
CC=cc bazel test --test_output=all -c dbg --config=asan --verbose_failures //test/core/transport/chttp2:http2_client_transport_test
```
```

It's not obvious to me what the reason for the increase in test time is, but it seems that we were already at ~3hr45min earlier and now we are timing out at 4 hours. Increasing to 6 hours.

Possible fix for sporadic flakes like `detected corruption in /Volumes/BuildData/tmpfs/altsrc/github/grpc/workspace_ruby_macos_dbg_native/src/ruby/lib/grpc/grpc_c.bundle` we've been seeing in ruby.
`rake` (invoked by run_ruby.sh) "shouldn't" be modifying the binary if it's already been built (which is the case in these tests) but isn't really guaranteed not to. Running rspec directly ensures that we don't accidentally write to any pre-built artifacts while tests are possibly using them.
A side benefit here is to get better test reporting granularity.

Follow up from #37917 to add `noexcept` to multiple Cython functions using `nogil` with a `void` return type.
Below are the performance hints that were encountered as part of the Cython translation which are solved by this PR:
The below performance hint still exists, and is not resolved.
This is because `noexcept` expects that the function doesn't raise an exception, or a raised exception is just displayed as a warning and not propagated. But `_poll` raises an `AssertionError` at `QUEUE_TIMEOUT`, and hence cannot use `noexcept` with `_poll`.
As [PR 37917](https://github.com/grpc/grpc/pull/37917) and this PR now solves the Cython Asyncio test timeouts caused by Cython upgrade, this PR also reverts the Bazel Cython downgrade PR #37884
### Testing for timeout
Tested using `bazel test -c dbg --runs_per_test=3000 --test_timeout=10 "//examples/python/auth:_auth_example_test"`
```
//examples/python/auth:_auth_example_test PASSED in 4.6s
Stats over 3000 runs: max = 4.6s, min = 2.6s, avg = 3.2s, dev = 0.2s

This aims to resolve segfaults encountered when rebuilding ARM64 PHP Docker images. This segfaults came from gcc during ARM64 builds using QEMU. To workaround this problem, the PHP Docker images have been restructured to use apt-get for installation, thereby avoiding the use of gcc. This also needed to upgrade Debian and PHP to their latest versions, aligning with our minimum supported PHP 8.
