    pipeline: make _GET_LAYER_NO_CREATE enum a flag
    
    _cogl_pipeline_get_layer_with_flags accepts a CoglPipelineGetLayerFlags
    flags argument and understands one COGL_PIPELINE_GET_LAYER_NO_CREATE
    flag. There was a mistake with the definition of this enum though so
    COGL_PIPELINE_GET_LAYER_NO_CREATE had a value of 0 and so testing for
    the flag using the bitwise & operator would never find the flag set.
