EventRouterForwarder::DispatchEventToRenderers() is used to dispatch an event to extension listeners in a particular profile. The only utility of it over using EventRouter directly is that it allows it to be called from threads other than the UI thread. However, in practice, this is only used in one place (the Proxy API) and is always called from the UI thread. Remove it from EventRouterForwarder and place it directly in the Proxy API. This CL should have no behavior change.
