Github CI/CD: checkout@v4, macos matrix updates

- Per Github messages, upgrade checkout@v3 to checkout@v4 due to an
  upgrade to Node.js.

- macos-11 is now a defunct image runner. Homebrew packages either have
  to compile from source or no longer install correctly.

- Update the macos compile matrix. Set CPACK_SUFFIX environment variable
  to indicate macOS hardware platform: macos-14 is M1, whereas macos-12
  and macos-13 are x86_64.
