Add debug info for macOS CI actions

This adds some debugging information to the CI logs about the macOS runners to potentially help diagnose performance issues. I think this is unlikely to help, since I think the most likely issue is over-provisioning, but I figured it might be a worthy shot in the dark. The macos-12 runners definitely have issues with SIP randomly being enabled, but I have not seen evidence of that for macos-13.
