Preparation for switching away from `grpc_channel_filter*` to identify channel filters.

This change brings up the direct channel, and inproc promise based transports.
This work exposed a bug that was very difficult to fix with the current call_filters.cc implementation, so I've substantially revamped that - instead of having a pipe-like object per call element, we now have a big ol' combined state machine for the entire call. It's a touch more code, but substantially easier to reason about individual cases, so I much prefer this form (it's also a slight memory improvement: 12 bytes total to track call state, and 10 of those are wakeup bitmasks...).

All TraceFlags are now configured in `src/core/lib/debug/trace_flags.yaml`. The format is:
```
my_flag:
default: false # the default value; default=false
description: Some Description
debug_only: false # debug_only flags only work in debug builds; default=false
internal: false # internal flags will not show up in documentation; default=false
```
To regenerate the trace flag source code, run `tools/codegen/core/gen_trace_flags.py` (requires mako). This script is also run when sanity checking.
This PR also adds two new features:
### Glob-based flag configuration
Trace flag configuration now supports `?` (single wildcard character) and `*` (one or more wildcard characters). For example, using `GRPC_TRACE='event_engine*'` will enable all flags that match that glob. It expands to:
* event_engine
* event_engine_client_channel_resolver
* event_engine_dns
* event_engine_endpoint
* event_engine_endpoint_data
* event_engine_poller
### A cleaner trace-logging macro in abseil logging format
If your goal is only to add log statements when the `fault_injection_filter` trace flag is enabled, you can use the macro:
```
GRPC_TRACE_LOG(fault_injection, INFO) << "Filtered:" << 42;
```
When the trace flag is enabled, the the log will show something like this:
```
I0000 00:00:1715733657.430042 16 file.cc:174] Filtered:42
```
----
Note: just like with the gpr_log to abseil logging conversion, the pre-existing trace logging usages can be replaced with the new tracing macro across multiple PRs.

Introduce "Yodel" - a framework for testing things vaguely related to calls.
This is breaking up some work I did for transport test suites - we've got a nice way of spawning test-only promises and tracking them visually, and support for setting up an environment that can run as a test or a fuzzer. I'm making that piece a little more reusable, and then rebasing the transport test suite atop that infrastructure.

Not the fastest implementation possible, but it's a log helper so I'm not particularly fussed either -- but a useful utility that we can iterate on later to help debugging.

### 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.

This is a prerequisite for the upcoming Protobuf v26 upgrade and has the following changes;
- Reduced the optimization level from `O3` to `O1` on Linux to workaround a segfault issue on `manylinux2014/x86`. This is believed to be caused by an aggressive but buggy optimization that `gcc` 10 made so workaround is to reduce the optimization level. `gcsio_tools` isn't that performance sensitive so we should be able to afford this change. (internal b/329134877)
- Added a Windows library dependency `Shell32.lib` to support the use of `CommandLineToArgvW`. (internal b/328455319)

The stubs generated by grpcio_tools should always be used with [the same or higher version of grpcio](https://github.com/grpc/grpc/blob/master/tools/distrib/python/grpcio_tools/setup.py#L313), this change will add a run time check for this requirement inside the generated stubs and therefor enforce this requirement.
Please note for now we're just printing a warning for incorrect usage, we'll **change it to an error** soon.
Example warning message:
```
/usr/local/google/home/xuanwn/workspace/misc/grpc/examples/python/helloworld/helloworld_pb2_grpc.py:21: RuntimeWarning: The grpc package installed is at version 1.60.1, but the generated code in helloworld_pb2_grpc.py depends on grpcio>=1.63.0.dev0. Please upgrade your grpc module to grpcio>=1.63.0.dev0 or downgrade your generated code using grpcio-tools<=1.60.1. This warning will become an error in 1.64.0, scheduled for release on May 14,2024.

Protobuf is beginning to rely more on upb, pulling in more C files. Hence, grpcio_tool needs the following changes to absorb this.
- Changing the setup.py to support both C and C++ by removing explicit language=c++. Rather it can choose the right compiler by its extension.
- Adding build_extensions injection to deal with C/C++ option conflict as grpcio does.
- Adding protobuf and upb directories to the build script so that it can find newly added source files in protobuf.

We changed `pkg_resources.resource_filename` to `importlib.resources.files`, but the return of `resources.files()` API is a traversable object implementing a subset of the [pathlib.Path](https://docs.python.org/3/library/pathlib.html#pathlib.Path) interface instead of string, thus we're seeing errors like `AttributeError: 'PosixPath' object has no attribute 'rstrip'`.
This PR converts the result of `files()` to str to prevent those kinds of errors.

This PR is required in order to upgrade to the `master` branch version of protobuf. To do this, we upgrade to the latest version of `rules_python` by:
- Adding in explicit dependencies on all PyPi Bazel test dependencies
- Resolving the circular dependency this creates for `xds-protos` by giving it a Bazel build
- Generating the Python code for `xds-protos` as part of `generate-projects.sh` since doing so directly in Bazel would be highly fragily, dependent on many other projects' Bazel builds

[Implement OpenTelemetry PR](https://github.com/grpc/grpc/pull/35292) was [reverted](96b9e8d3e3) because some tests started failing after import the changes to g3.
After investigation, we found root cause, it can be fixed both on our side and on gapic API side, we opened an issue to [gapic API team](https://github.com/googleapis/python-api-core/issues/579), this PR will includes the fixes on our side.
