Source/WebKit2:

The new InsetClipLayer and ContentShadowLayer members on scrolling nodes
need to be correctly encoded/decoded for UI-side compositing, and dumped
correctly.

(ArgumentCoder<ScrollingStateScrollingNode>::encode):
(ArgumentCoder<ScrollingStateScrollingNode>::decode):
(WebKit::RemoteScrollingTreeTextStream::dump):
