Closes#35932
PiperOrigin-RevId: 612639020
This adds the following new targets:
- `channel`: A virtual interface for a channel.
- `legacy_channel`: A channel implementation that supports the filter stack and call v2.
- `channel_create`: A standalone function to create a channel.
- `server_interface`: A base class with a few accessor methods used in surface/call.cc.
- `server`: The actual server implementation.
- `api_trace`, `call_tracer`, `server_call_tracer_filter`, `call_finalization`: These were split out of `grpc_base` to avoid various dependency problems.
- `compression`: This is a combination of the previously existing `compression_internal` target and the compression code that was part of `grpc_base`.

This breaks the following pieces out of the `grpc_client_channel` BUILD target:
- backend_metric_parser
- oob_backend_metric
- child_policy_handler
- backup_poller
- service_config_channel_arg_filter
- client_channel_channelz
- client_channel_internal_header
- subchannel_connector
- subchannel_pool_interface
- config_selector
- client_channel_service_config_parser
- retry_service_config_parser
- retry_throttle
The code left in the `grpc_client_channel` target will need more work to pull apart.

Core team [moved resolver code](https://github.com/grpc/grpc/pull/35804) to `src/core/resolver`, our build is failing because we have a dependency on it and the resolver folder is not copied to `observability/grpc_root`:
* `call_tracer.h` -> `core_configuration.h` -> `lb_policy_registry.h` -> `lb_policy.h` -> `endpoint_addresses.h`
To fix this issue and to prevent such issues from happening again, instead of subfolders, we'll copy all files from `src/core` to `observability/grpc_root/src/core`.

This PR changes the implementation of `maximum_concurrent_rpcs` flag in AIO stack to match the docstring.

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

A call execution environment for the V3 runtime.
The `CallFilters` class will ultimately be a (private) member of `CallSpine`, and the `StackBuilder` component will be used by a channel when all of the filters it needs are known to allow the call spine to start processing a call.
This is accompanied by a reasonably extensive test suite.
I expect to fine tune semantics, implementation, and tests over the coming weeks/months as we iterate to bring up the rest of the pieces.

Fix: https://github.com/grpc/grpc/issues/35086
Starting Python 3.12, `asyncio.get_event_loop()` will [emit deprecation warning](https://docs.python.org/3/library/asyncio-eventloop.html#asyncio.get_event_loop) if there is no current event loop.
Since we're calling `get_event_loop()` in case there is no running loop, it make sense to use `new_event_loop()` instead.
