Subject: [PATCH] Bug 35248: Refactor - Move assign_item_for_booking

This routine really belongs inside Koha::Booking rather than
Koha::Biblio. This patch moves it there, renames with _ to highlight
it's private nature.

Test plan
1) Confirm that t/db_dependant/Koha/Booking.t still passes, specifically
   the 'store' test.
