[FYI] Windows builds on push to main

I’ve changed the Windows builds to run on every push to main, so developers get notified when their patch broke the Windows build. The Windows build is currently broken ( [FIRRTL] InferResets: Windows build broken · Issue #1565 · llvm/circt (github.com)).

The tests on Windows are also broken (Windows test failures · Issue #376 · llvm/circt (github.com)), but once they’re working I’ll enable them as well.

It’s looking like my internal user base might be increasing in the near future. Unfortunately, we run Windows nearly everywhere internally. So it’s gonna be important that the Windows version actually works.
