dispatchLoadEventForFrameOwner() might be a bit more consistent with how things
in the Blink API layer are named.

As an aside, it feels like it should be possible to integrate this somehow with
the didStart/didStopLoading stuff, but the current structure is fine.

Done.

I can double-check with Nasko about didStart/didStopLoading.  I noticed that
FrameOwner::dispatchLoad is also dispatched when the load is canceled because of
XFO or CSP, so it may not be exactly the same.

     virtual void didStopLoading() = 0;
