Generate native image for Windows

[olafurpg]

Currently, our CI generates GraalVM native images for Linux and macOS.

https://github.com/scalameta/scalafmt/blob/master/.github/workflows/native.yml

It would be nice if we also automaticlly generated a native image on Windows. It looks like GraalVM native-image also works on Windows but it requires a custom environment that I haven't been able to reproduce on GitHub Actions.

Hi, @olafurpg! I know this is old and probably not relevant anymore, but I have a recent example that does that: https://github.com/nikololiahim/polystat-cli/blob/master/.github/workflows/release.yml. I have a question: what is necessary to running native-image binaries generated without --static on macos? I don't have a mac, so I can't check it. I have not seen many repositories that do this, so I may want to borrow your setup :)
