Run CI Tests on both MacOS Arm and x86

[notatallshaw]

It occured to me that pip tests currently only run on MacOS x86, which at this point could be considered problematic.

Checking the documentation (https://docs.github.com/en/actions/using-github-hosted-runners/about-github-hosted-runners/about-github-hosted-runners#standard-github-hosted-runners-for-public-repositories) it appears that you must manually specify which version of MacOS you want to get the Arm version.

This probably could be done a little more elegantly but first I wanted to see if all tests would pass on Arm.

[notatallshaw]

Well they pass, and complete faster than any of the other workers, so seems like there's little reason not to enable?

Marking ready for review.

Pip's macos-latest runner is now macos-14 causing pip CI to fail: https://github.com/pypa/pip/actions/runs/8825862850/job/24230722241

This PR supports continuing to test x86 and ARM, where as my alternative PR fixes pip CI just for ARM: #12617

This failure is new:

FAILED tests/functional/test_install.py::test_vcs_url_urlquote_normalization - pip._internal.exceptions.InstallationSubprocessError: bzr checkout --lightweight --quiet http://bazaar.launchpad.net/%7Edjango-wikiapp/django-wikiapp/release-0.1 /private/var/folders/hv/qqnln7cj5cg0n48fcrlmbz4m0000gn/T/pytest-of-runner/pytest-1/popen-gw1/test_vcs_url_urlquote_normaliz0/cache/release-0.1 exited with 3

I guess it's a flaky test? I have no way to try to reproduce.

Yup, I forced CI to rerun and this time the test passed.

So this PR is updated to run MacOS 12 (x86) on all versions of Python, and MacOS Latest (M1) on Python versions >= 3.10, as 3.8 and 3.9 have a failing test (test_uninstall_editable_from_usersite).

[notatallshaw]

FWIW, I think this PR is worth merging, macos-latest runs much faster so it doesn't slow down the CI, and either someone else can fix Python 3.8 and 3.9 tests on MacOS ARM, or eventually they will go end of life and it won't be an issue any more.

Can a maintainer yay or nay this, I'll close the PR if nay.

To summaraize:

• CI tests are currently running against macos-12 (x86)
• This PR adds CI macos-latest (arm) for Python 3.10+
• Last I checked macos-latest (arm) fails test_uninstall_editable_from_usersite on Python 3.8 and 3.9, I have no way to locally reproduce

I'm closing this PR as I don't like keeping PRs open and stale.

It's very easy for someone else to recreate, and I've made a GitHub issue to be tracked #12908
