LibWeb: Measure the overflow for all scroll containers

Browse source 
Instead of just measuring the layout viewport, we now measure overflow
in every box that is a scroll container.

This has the side effect of no longer creating paintables for layout
boxes that didn't participate in layout. (For example, empty/anonymous
boxes that were ignored by flex itemization.)

Such boxes are now marked as "(not painted)" in the layout tree dumps,
as they have no paintable to dump geometry from.
