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.

This PR:
- Fixes the xds-protos Python package, which was broken when the `udpa`
submodule was removed
- This required re-adding the protoc-gen-validate submodule
- Adds non-Bazel tests for xds-protos and all of its dependent packages
- Versions xds-protos the same way as the rest of the Python packages
- Fixes Python 3.11 support in `run_tests.py`, which is necessary for
the testing mentioned above
CC @sergiitk You won't be able to consume this in the interop tests
until it makes it into a release. I'm thinking I'll want to backport
this to the 1.57.x branch to make that happen faster.
CC @drfloob to inform him about the likely backport.
