[MylesBorins]

A couple changes have landed upstream, it would be nice to track all three being backported

/cc @refack @joaocgreis

• build,windows: Implement python detection
• build,win: use latest installed VS by default and respect VS version for building addons
• build,windows: fix vcbuild.bat

[MylesBorins]
