[Python 3.12] Deprecate distutil (#34186)
### 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.
