LP#1621178: Tweaks to item status column picker option

This commit:
* Sets copy status as visible by default on the Item Status list page
* Removes the copy status column from the Checkout page. The expectation is
that items will not appear in this grid unless they have a Checked out status.
* Adds the copy status to the holds pull list. This is mostly useful for staff
to see if an item was recently returned, and most likely to be found on the
reshelving cart.
