REVISION SUMMARY
  Note: most of the foundational work of this commit was done by Matt Harbison,
  but enough has changed that I don't feel comfortable sending this patch as his.
  
  In our quest to remove Python 2 from Mercurial, we need to get Windows CI going
  to check that Python 3 support is up to an acceptable standard.
  This is the first step: adding a manual step to run a full Windows CI, with a
  certain definition of "full" since some things are not installed yet, like SVN.
