[cogl] Make _cogl_pipeline_get_layer_texture public

    Make _cogl_pipeline_get_layer_texture public
    
    There was no other way to get a pointer to the texture attached to a
    pipeline layer apart from the using the CoglMaterial API but I think
    this was just an oversight so we should add this in. It is already
    maked in the sections file for the gtk-doc.
