Call cogl_xlib_renderer_set_threaded_swap_wait_enabled()

Set up things so that if the INTEL_swap_event extension is not present,
but the driver is known to have good thread support, we use an extra
thread and call glXWaitVideoSync() in the thread. This allows idles
to work properly, even when Mutter is constantly redrawing new frames;
otherwise, without INTEL_swap_event, we'll just block in glXSwapBuffers().
