[Layout API] Use more layoutViewItem() in Document
follow-on to https://codereview.chromium.org/2126973004
Document::layoutView() is deprecated and being removed soon. The
replacement is Document::layoutViewItem(), which routes methods
through the new block layout API. (See linked crbug for details.)
No new layout API methods were required in this CL.
There are no functional changes.
