`MGLStyleLayer` was updated to support a raw pointer to the mbgl object, which is always initialized, either to the value returned by `mbgl::Map getLayer`, or for independently created objects, to the pointer value held in `pendingLayer`. In the latter case, this raw pointer value stays even after ownership of the object is transferred via `mbgl::Map addLayer`.
