  [IFC][Partial layout] Issue full repaint even for partial layout when relayoutChildren flag is set

This is in preparation for turning on partial layout on text change.

With partial layout disabled, we always issue full repaint when invalidating the line layout path (see RenderBlockFlow::invalidateLineLayoutPath). It covers cases explained in RenderBlockFlow::layoutModernLines.
