LibWeb: Invalidate the display list when calling set_needs_display()

Calls to `Document::set_needs_display()` and `Paintable::set_needs_display()` now invalidate the display list by default. This behavior can be changed by passing `InvalidateDisplayList::No` to the function where invalidating the display list is not necessary.
