Add Windows ARM64 support in CI

[Harishmcw]

This PR adds Windows ARM64 support to the CI build and test matrix for zope.interface.

• Adds windows-11-arm to the os matrix in both build-package and test jobs.

• Excludes pypy-3.11 and 3.10 for windows-11-arm as they are not supported on Windows ARM64.

• Splits the artifact upload/download steps into separate Windows and Linux steps, using runner.arch in the artifact name for Windows to avoid naming conflicts between windows-latest (X64) and windows-11-arm (ARM64).

• I signed and returned the Zope Contributor Agreement, and received and accepted an invitation to join a team in the zopefoundation GitHub organization.

@Harishmcw Thank you for your pull request.
I think you are aware that you are changing a file here which says on its top:

# Generated with zope.meta (https://zopemeta.readthedocs.io/) from:
# https://github.com/zopefoundation/meta/tree/master/src/zope/meta/c-code

So your changes will be gone on the next run of the template if the template is not updated to support windows ARM.

Hi @icemac,

Thanks for the feedback!

I've raised a PR to zopefoundation/meta to make the changes at the template level.
