RemoteScrollingTreeMac::deferWheelEventTestCompletionForReason() and RemoteScrollingTreeMac::removeWheelEventTestCompletionDeferralForReason()
would always trigger the hop to main thread, and IPC with the web process. We only need to do that when running layout tests
that use `eventSender.monitorWheelEvents()`, and the RemoteScrollingTree already has a bit for that, so use it.
