  [IFC][Integration][Line clamp] Add line clamp state to RenderLayoutState
https://bugs.webkit.org/show_bug.cgi?id=248130

Reviewed by Antti Koivisto.

Use RenderLayoutState to pass the current clamp state over to IFCs across nested RenderBlockFlow renderers (while line-clamp is set on -webkit-box, it is applied across the descendant block boxes).
