[cogl] texture: make cogl_texture_get_format api private

commit ffde82981f22bd0185a7f33e1e6e1479f4c295b8
Author: Robert Bragg <robert linux intel com>

    texture: make cogl_texture_get_format api private
    
    CoglPixelFormat is not a good way of describing the internal
    format of a texture because it's too specific given that we don't
    actually have exact knowledge of the internal format used by the driver.
    
    This makes cogl_texture_get_format private and in the future we'll
    provide a better way of querying the channels and their precision.
