Andreas Kling 7af03df4c3 LibWeb: Make Painting::Box virtual and add Painting::BoxWithLines ...

BlockContainer paint boxes are the only ones that have line boxes
associated, so let's not waste memory on line boxes in all the other
types of boxes.

This also adds Layout::Box::paint_box() and the more tightly typed
Layout::BlockContainer::paint_box() to get at the paint box from the
corresponding layout box.
