Alex Hornby 26616c4c75 getdeps: update github windows runner and internal CI to VS 2022 
Summary:
X-link: https://github.com/facebookincubator/fizz/pull/163

The github [windows-2019 actions image was retired by github](https://github.com/actions/runner-images/issues/12045),  so all jobs on it fail

Update to windows-2022 to get them running again

windows-2022 has [different tools and versions than windows-2019](https://github.com/actions/runner-images/issues/3949).  Notably it moves from Visual Studio 2019 (aka msvc 16.x) to Visual Studio 2022 (aka msvc 17.x), hence the update to buildopts.py discovery

In the course of regenerating the github actions I also fixed a couple of issues that stopped regeneration matching repo contents
  * a few workflows were using workflow_dispatch, added support
  * there were a trailing and double spaces for project_prefix, fixed (use ignore whitespace to remove this from review!)

# Tell setuptools to bypass its own search. This fixes a bug

# Actions with the inscrutable message 'error: Microsoft
# Visual C++ 14.0 is required. Get it with "Build Tools for
# Visual Studio"'. I suspect the actual error is that the
