RFR: 8318039: GHA: Bump macOS and Xcode versions

Thu Oct 12 19:34:41 UTC 2023

In GHA, the versions of macOS (note: the version used for build/test, **not** the target macOS version we compile for) and Xcode are starting to show age. It's time to update to more modern versions.

This change bumps the macOS to 13 (from 11) and Xcode to 14.3.1 (from 12.5.1/11.7). This is a prerequisite change for JDK-8317970 / #16155, without which the build SIGSEGVs (presumably some since-fixed issue in Xcode 12.5.1).
