    x11: Set up the compositing manager selection on meta_display_init_x11()
    
    This used to be set on meta_compositor_manage(), but only if there is a
    MetaX11Display. Given meta_display_init_x11() is Wayland only, and we can
    always assume compositing to be enabled, just have it invariably set after
    the X server is up.
