[copy-propagation] Since this runs on OSSA and we have formalized consuming there, use that instead of our own handrolled consuming use impl. This is in preparation for adding a run of this around ownership lowering in order to eliminate extra copies that passes may introduce as they transform IR. The tests for the pass all still pass in the exact same way so no updates were needed.
