platform: move builds and releases to Windows

Switch the GitHub Actions workflows to run on Windows instead of Ubuntu. This includes
the build, build-pr, and publish workflows, as well as the release job. Additionally,
update the gradle and gradlew.bat scripts for consistency with the new platform.
