LibWeb: Use separate structure to represent fragments in paintable tree
This is a part of refactoring towards making the paintable tree independent of the layout tree. Now, instead of transferring text fragments from the layout tree to the paintable tree during the layout commit phase, we allocate separate PaintableFragments that contain only the information necessary for painting. Doing this also allows us to get rid LineBoxes, as they are used only during layout.
