[IFC][Integration] Allow RenderView layout by IFC
https://bugs.webkit.org/show_bug.cgi?id=262705
rdar://116525525
Reviewed by Alan Baradlay.
In some cases (like if the document element has display:inline) root content
will be laid out by IFC.
We currently use the LFC initial containing block box as a place to parent
subtrees that are not
fully connected via ancestor chain (because we don't yet create layout boxes
for all blocks).
Because of this the natural solution of just making RenderView::layoutBox()
same as
RenderView::initialContainBlock() does not work. Instead this patch makes
RenderView::layoutBox()
return a separate box parented to the initial containing block box.

Ensure we delete line layout if it exits before we delete the initial
containing block.
