      resharding::data_copy::ensureCollectionDropped is currently taking a DB X lock. Since it only needs to drop a given collection, we can downgrade this lock to a DB IX lock instead, to help both resharding as well as other operations to finish faster.

       

      Note that taking a DB X lock was a change by SERVER-104155 so this only affects v8.2+.
