cogl-context: Remove the driver private data

Since the GL function pointers have move to the root of CoglContext,
the driver specific data for GLES became empty and the GL data had
only one varible which apparently nothing was using. It's therefore
convenient to remove the private driver data to make it easier to have
a build of Cogl which enables both GL and GLES support. If we ever
need driver private data later we might want to use
cogl_object_set_user_data instead.
