contrib: install VS BuildTools 2022 in the Windows dependency installer script
This is built on !1169. I left it separate in case it causes any headaches with updating setup.py and getting rid of distutils. AFAICT, it just works- I uninstalled the 2017 buildtools, installed this, and was able to build locally, build all wheels, and run the full test suite with py39 that gets built. So I think this is OK as-is.
