Disabling deprecated compatibility builds (#1944)

# Summary
- Temporarily disabling tests that use macos-12 runners ([deprecated by
github](actions/runner-images#10721))
  - Disables tests for iOS 15, 14 & 13 unfortunately
- Switching from macos-13-xl to macos-13 (for some reason there is no xl
runner anymore for macos-13)
