Enable windows tests

[samanklesaria]

Windows tests were disabled as dependency installation was failing. Now that most dependencies are removed, we should try again.

There are lots of changes in this PR that does not match the title. Is this PR (as it is) still relevant?

[samanklesaria]

This PR is really just for commit [0607381]. The rest are from merges with a pseudo-main branch that was used while PRs to the main branch were bottlenecked.

We're getting fatal error C1083: Cannot open include file: 'torch/csrc/stable/library.h': No such file or directory 2025-09-02T21:40:26.6551037Z . Perhaps the windows build isn't using pytorch nightly?

Now we're seeing "Cannot open include file: 'cuda_fp16.h': No such file or directory" for cuda builds.

The CTC decoder isn't being built even for the cuda jobs. Maybe that's okay for now? I think just getting the windows tests working, even if they don't test the ctc stuff, is a good place to have this PR.

CI is passing now! But we use conda run rather than activate. As #4085 uses the old "activate" style and also passes the tests, I will close this PR in favor of that one.
