ci: revise GHA worfklow for Windows

Run on all commits to `master` and PR branches.

Aim for consistency re: GHA workflows for macOS and Linux.

Also switch from mingw64 to ucrt64 and drop use of sudo, etc. that aren't
relevant on Windows + mingw-w64-ucrt-x86_64.

Add README badge for the GHA workflow for Windows - let's make the "red light"
turn into a "green light"!
