Reviewed by Sam Weinig.

macOS subclassed RemoteScrollingCoordinatorProxy into RemoteScrollingCoordinatorProxyMac, so do the same
for iOS. This cleans up some #ifdeffed code.

The RemoteLayerTreeDrawingAreaProxy subclasses instantiate the correct type of RemoteScrollingCoordinatorProxy.

Define SPECIALIZE_TYPE_TRAITS so we can use downcast<> etc but have the predicate be compile-time.
