Subject: [PATCH] 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.
