[CSS Regions] Move named-flow specific method decorationsClipRectForBoxInRegion to RenderNamedFlowThread
https://bugs.webkit.org/show_bug.cgi?id=129428
Reviewed by Andreas Kling.
Since the decorationsClipRectForBoxInRegion method is a named flow specific method, it makes
sense to be in the named flow specific class, RenderNamedFlowThread, instead of the more
generic RenderFlowThread.
No new tests required. No new functionality.
