Add graalpy early-access and windows builds

[timfel]

Description:
This adds two things:

1. Windows builds of GraalPy are now available that are useful enough to enable for users. Some minor fixes to our scripts were needed, tests were updated to run on Windows as well.
2. We make early access builds of upcoming versions available in a separate repository, these are now also available.

Related issue:
#693 and the question after Windows support by @kurtmckee in #694 (comment)

Check list:

• [ ] Mark if documentation changes are required. None required.
• Mark if tests were added or updated to cover the changes.

Hi @dmitry-shibanov, since you reviewed the original GraalPy PR, maybe you have a chance to look at this?

@aparnajyothi-y please let us know if there is anything we can help with. In case it helps, GraalPy EA builds are released under GFTC, the same license as Oracle GraalVM, which is integrated into setup-java.
