Replace retired macOS 14 runner and test all available Xcode versions

GitHub retires the macos-14 image on 2026-11-02 (brownouts from
2026-10-05). Xcode 15 is not available on any remaining hosted
runner, so drop the macos-14 job and its documented compilers.

Also test the Xcode versions that the images provide but CI did not
use (26.1.1-26.3 on macos-15, 26.4.1-26.6 on a new macos-26 job), and
pin GCC 16 explicitly next to gcc:latest.
