Convert EventRouter to use ProcessMap::GetMostLikelyContextType rather than

Convert EventRouter to use ProcessMap::GetMostLikelyContextType rather than
implementing its own process checking logic, and (double) check on event
dispatch that the context has permission to receive the event. Currently we
only check on event registration.

Please [triple] check this.

I'm wondering if there's some way we can unify the logic here with the logic in
Dispatcher::ClassifyJavaScriptContext. Doesn't look easy.

In any case this LGTM

Yeah, good idea. I can look into this after this patch, this seems like an
improvement + step in that right direction.
