### Background
* `distutils` is deprecated with removal planned for Python 3.12
([pep-0632](https://peps.python.org/pep-0632/)), thus we're trying to
replace all distutils usage with setuptools.
* Please note that user still have access to `distutils` if setuptools
is installed and `SETUPTOOLS_USE_DISTUTILS` is set to `local` (The
default in setuptools, more details can be found [in this
discussion](https://github.com/pypa/setuptools/issues/2806#issuecomment-1193336591)).
### How we decide the replacement
* We're following setuptools [Porting from Distutils
guide](https://setuptools.pypa.io/en/latest/deprecated/distutils-legacy.html#porting-from-distutils)
when deciding the replacement.
#### Replacement not mentioned in the guide
* Replaced `distutils.utils.get_platform()` with
`sysconfig.get_platform()`.
* Based on the [answer
here](https://stackoverflow.com/questions/71664875/what-is-the-replacement-for-distutils-util-get-platform),
and also checked the document that `sysconfig.get_platform()` is good
enough for our use cases.
* Replaced `DistutilsOptionError` with `OptionError`.
* `setuptools.error` is exporting it as `OptionError` [in the
code](https://github.com/pypa/setuptools/blob/v59.6.0/setuptools/errors.py).
* Upgrade `setuptools` in `test_packages.sh` and changed the version
ping to `59.6.0` in `build_artifact_python.bat`.
* `distutils.errors.*` is not fully re-exported until `59.0.0` (See
[this issue](https://github.com/pypa/setuptools/issues/2698) for more
details).
### Changes not included in this PR
* We're patching some compiler related functions provided by distutils
in our code
([example](ee4efc31c1/src/python/grpcio/_spawn_patch.py (L30))),
but since `setuptools` doesn't have similar interface (See [this issue
for more details](https://github.com/pypa/setuptools/issues/2806)), we
don't have a clear path to replace them yet.

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.

This version broke backward compatibility in `plugin_pb2.py`, which is
presumably a relatively minor regression, since we have not yet heard
any complaints about it. This PR:
- Excludes `4.22.0` from installation
- _Includes_ protobuf pre-releases into testing so this can be caught
more quickly in the future.
When bad prereleases are caught, we can exclude them from testing in a
similar manner to this PR. We may eventually want to invest into a
system where we can define these bad versions centrally.
