LibWeb: Prune old paintable pointers from layout tree after relayout
When text paintables shift around in the tree due to line wrapping, we may end up in a situation where some text node does not generate a paintable (due to being all whitespace, for example), even though in the previous layout pass, it *did* generate a paintable. To prevent holding on to old paintables in such cases, we now do a pass in LayoutState::commit() where we explicitly detach all old paintables from the layout tree.
