Remove legacy msvc compiler modules.

[jaraco]

They were marked as deprecated in c802880, so they shouldn't be in use.

Notwithstanding that these shouldn't be in use, in practice these appear to be used by cffi, and thus this change breaks cffi: https://github.com/python-cffi/cffi/blob/main/src/cffi/_shimmed_dist_utils.py#L33

I'll file a cffi bug about fixing this.

It also broke gnome: https://gitlab.gnome.org/GNOME/gobject-introspection/-/issues/515

If you have a reference to the downstream report, that would be helpful to follow. I looked briefly into the other issues and I don't think there's anything this project should do, though I could consider re-adding some interfaces to restore compatibility for a limited duration, but only if there's a compelling case. In general, I expect users reliant on these older modules to be in a precarious state anyhow.

For pygame the setuptools for windows msvc compilers have been pinned to previous setuptools version. I haven't looked yet on how to update the code which uses the compiler yet. It's here if you're interested: https://github.com/pygame/pygame/blob/main/buildconfig/vstools.py

I know not everyone can pin their packages to previous versions of setuptools. But for anyone that can pin whilst they fix, I wrote instructions here: pypa/setuptools#4620 (comment)

Looks like the cffi "usage" is an ancient and mostly-dead monkeypatch- spinning an updated CFFI release now that makes the import/patch optional until we're sure it's "all dead" and can go through its pockets for loose change 😉.
