setup: handle removal of old MSVC compiler from setuptools 65.0 (issue6910)

It was removed a few years ago[1].  When trying to reproduce locally using a
clean py3.12 as called out in the bug report, `setuptools` wasn't installed at
all, and needed a `pip install` to fix a `ModuleNotFoundError` when building
locally.  Maybe that needs to be in the requirements clause now.

It looks like this "private" module was added in setuptools 48.0.[2]  I can't
find a changelog of what version was included in which version of python, and
the changelog for pip has a huge gap between when it called out 67.6.1 in `pip`
23.1 (2023-04-15), and 41.4.0 in `pip` 19.3 (2019-10-14).[3]  So, we'll just add
to the existing code instead of replacing it, for safety.
