LibWeb: Make TextNode::ChunkIterator emit an empty chunk for content:""

Browse source 
This ensures that we create a line box for content:"", which would
otherwise get pruned by the empty line cleanup in IFC.

The empty line box is important in this case, since it gives us a
reference point for measuring the automatic height of the IFC's
containing block. By having an empty line, we can now correctly measure
the impact of vertical margins on a generated box with content:""
and allow them to contribute to the block height.
