Build aarch64 wheel on the new arm64 runner (and test it)

[saschanaz]

GitHub just added arm64 Windows runner: https://github.blog/changelog/2025-04-14-windows-arm64-hosted-runners-now-available-in-public-preview/

#246 added some hack to build arm64 on x64, maybe it can go away if we build it natively.

Indeed support just landed but is not yet released, probably very soon pypa/cibuildwheel#2362

@saschanaz and @ofek I believe, the PR I have raised should fix this issue and wheels would available for Win-ARM64 officially soon
