[clutter/wip/cogl-winsys-glx: 6/20] Remove unused _cogl_swap_buffers_notify

[Robert Bragg <rbragg src gnome org>]

commit e381a159a7b978ec61fc9e3d3e555e651dab42bb

    Remove unused _cogl_swap_buffers_notify
    
    Recently _cogl_swap_buffers_notify was added (in 142b229c5c26) so that
    Cogl would be notified when Clutter performs a swap buffers request for
    a given onscreen framebuffer. It was expected this would be required for
    the recent cogl_read_pixel optimization that was implemented (ref
    1bdb0e6e98db) but in the end it wasn't used.
    
    Since it wasn't used in the end this patch removes the API.
