[LayoutNG] Use legacy borders when painting table cell fragments

NG fragments don't support collapsed borders yet. This manifested with
background-clip. When the position/size of the clipped background was
determined, the cells' full borders were used, not half of the winning
border as is correct in collapsed mode.
