    testsuite: Add test setups for backends
    
    Add test setups that set the GDK_BACKEND and
    TEST_OUTPUT_SUBDIR environment variables.
    
    This lets use run
    meson test --setup x11 --suite reftest
    meson test --setup wayland --suite reftest
    and the output will be nicely separated.
    
    We still need to do compositor / display server
    setup from the outside.
