Subject: [PATCH] [CI] Add macos-latest cmake job to GHA workflow build tests

Test the build process of XRootD and the Python bindings on the
macos-latest virtual machine provided by GitHub Actions virtual
environment. The necessary build dependencies are provided by
the already installed XCode environment and through Homebrew
installs.
