[CI] Add more Windows hung test checks (#16859)

Obviously we shouldn't have to do this, but these hang issues are
causing serious CI issues and annoying users.

If there is a hung test detected, CI will fail after killing the
process, so we should still catch the hung tests.

I can't add an action instead of downloading the script because you need
to do a (cached) checkout to get the action file and that tries to reset
the git repo which fails if there's locked files.
