In #22202 the process delete method removeProcessPermanently was rewritten to do the whole batch of delete requests, then check for errors and refresh the display at the end. This is more efficient (it isn't refreshing the list after every delete request) and also combines the results into a single snackbar instead of 50.

For this ticket, we want to do something similar with the MOVE_TO_TRASH operation: send all the trash requests in a batch, and only update the user interface on completion. This probably involves changing toggleCollectionTrashed to take a list of uuids.
