Add a new RenderViewHostObserver interface for filtering IPCs send to RenderViewHost. This is needed because with TabContentsObserver, an observer might not know which RenderViewHost a message came from duing a pending navigation. A side-benefit is that we only have to add these observers once, instead of remembering/knowing all the delegates that might want to filter these messages.BUG=78629
