Title: filters for custom order item information on oi display tables

Subset of #6291 . Allows plugins to add additional order item information, above the order item meta printout, on the order confirmation screen order item table and on the order email order item table. (think additional 'link' to an order item asset, like a printable ticket, or some other custom, distinguishing feature of the order item that does not live in the order item meta)
