Remove calls of PrerenderTracker::TryCancel and TryCancelOnIOThread in ChromeResourceDispatcherHostDelegate. These short-circuited cancelling the prerendering on the IO thread. Instead, I moved cancelling the prerender on the UI thread since both of these calls end up going to the UI thread right after.

This also removes the last calls of ResourceRequestInfo::GetAssociatedRenderView, which I will remove in a followup.
