Add | column separators to arrays.

This adds the ability to add `|` to a column description and have
vertical separators be added. I added types to the column descriptions
and added some logic to handle the separators when building the vertical
lists of the array.

Test plan:
 - See the Arrays screenshot looks good.
 - `make test`
