[clutter] cogl-renderer: Move the XEvent filters to be generic for all renderers

    cogl-renderer: Move the XEvent filters to be generic for all renderers
    
    Instead of having cogl_renderer_xlib_add_filter and friends there is
    now cogl_renderer_add_native_filter which can be used regardless of
    the backend. The callback function for the filter now just takes a
    void pointer instead of an XEvent pointer which should be interpreted
    differently depending on the backend. For example, on Xlib it would
    still be an XEvent but on Windows it could be a MSG. This simplifies
    the code somewhat because the _cogl_xlib_add_filter no longer needs to
    have its own filter list when a stub renderer is used because there is
    always a renderer available.
    
    cogl_renderer_xlib_handle_event has also been renamed to
    cogl_renderer_handle_native_event. This just forwards the event on to
    all of the listeners. The backend renderer is expected to register its
    own event filter if it wants to process the events in some way.
