[cogl] framebuffer: Add _get_XYZ_bits() functions

[Robert Bragg <rbragg src gnome org>]

commit dcb033489ec770b751255d9367940d22adee39c4
Author: Robert Bragg <robert linux intel com>

    framebuffer: Add _get_XYZ_bits() functions
    
    This exposes the previously internal only
    _cogl_framebuffer_get_red/green/blue/alpha_bits() functions as 2.0
    experimental API.
