layout: Paint collapsed table borders on their own (#35075)

Browse source 
We were previously splitting collapsed borders into two halves, and then
paint each one as part of the corresponding cell. This looked wrong when
the border style wasn't solid, or when a cell spanned multiple tracks
and the border wasn't the same for all of them.

Now the borders of a table wrapper, table grid or table cell aren't
painted in collapsed borders mode. Instead, the resulting collapsed
borders are painted on their own.
