Add api for queuing idle callback internally

This adds a _cogl_poll_renderer_add_idle api that can be used internally
for queuing an idle callback without needing to make any assumption
about the system mainloop that is being used. This is now used to avoid
having the _cogl_poll_renderer_dispatch() directly check for all kinds of
events to dispatch, and to avoid having the winsys dispatch vfuncs need
to directly know about CoglContext. This means we can now avoid having a
back reference from CoglRenderer to the CoglContext.
