Reviewed by Tim Horton.

with macOS UI-side compositing, we'll continue to map coordinates through the
ScrollView's scroll position (and top content inset), as we do with web process
compositing. So the coordinate mapping functions in ScrollView should only
return early in the "scrolling handled by native view" case.

(WebCore::ScrollView::contentsToView const):
