LibWeb: Fix "background-clip: text" for elements nested in scrollable

Instead of carrying the display list for a mask in each command that
might potentially be affected by "background-clip: text", this change
introduces a new AddMask command that is applied once for all
background layers within one box.

The new AddMask command includes a rectangle for the mask destination
that is translated by the corresponding scroll offset.
