Can we add a comment? It's not obvious whom this method reports the timing. (At
RawResource layer it's slightly more obvious since its client has corresponding
method but at Resource layer it looks a bit puzzling...)

Added a comment. Also renamed it to more verbose name,
reportResourceTimingToWorker, hoping to make it clearer.
