Reviewed by Simon Fraser.

This is part 1 of splitting up https://github.com/WebKit/WebKit/pull/23242. The
purpose of this patch is to mark scrolling tree nodes that have an associated
RemoteFrame, currently using the LayerHostingContextIdentifier. This will later
be used to connect the scrolling tree from the iframe process in the ui process.
