+1 for moving the gcc level to 12

Along with nodejs/node#53561, we should also upgrade the minimum Xcode and Clang versions.

Newer V8 versions cannot be compiled by the ones we have in macOS 11.

We would need at least Xcode 16 for good C++20 support: https://developer.apple.com/xcode/cpp/#c++20, which is annoying as that version hasn't even been released yet!

Given https://endoflife.date/macos and nodejs/node#53561, I suggest we bump the CI versions to macOS 13.

From discussion in the meeting today, sounds like for 23 we are not ready to move to clang so we won't include in this release.
