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`.

Currently the implementation of `maximum_concurrent_rpcs` flag in AIO is different with docstring, in implementation, we're waiting for RPCs to finish and continue execution instead of raising `resource_exhausted` as mentioned in docstring.
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.

Based on [OpenTelemetry Metrics gRFC](https://github.com/grpc/proposal/blob/master/A66-otel-stats.md#opentelemetry-metrics), we should recored unregistered RPC method name as `other`, this PR adds the ability to pass register method information when creating a call.
We'll consider calls created using generated stubs as registered, note that this won't prevent user from setting `registered_method=True` when creating calls manually.
This is also enabled for simple stub flow but **NOT enabled for AsyncIO**, we'll add that later when start working on AsyncIO Observability.

[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.
