    testsuite: Setup tests env by platform
    
    Check whether we really have x11 and wayland enabled before we try to setup the
    tests to use these respective GDK backends, and only attempt to setup tests
    running with the Broadway backend if it has been enabled.
    
    Also, add a setup for running tests with the GDK-Win32 backend on Windows, for
    builds that target Windows.
