  [UI-side compositing] Ensure that wheel events got to the web process for JS 
event handlers
https://bugs.webkit.org/show_bug.cgi?id=248846

Reviewed by Tim Horton.

Override `eventListenerRegionTypesForPoint()` in RemoteScrollingTreeMac just as 
we do in ScrollingTreeMac
to get the event handler details for a given point. We use this to know if we 
have to continue with the
web process/main thread event handling path.
