Change Details

Add which outputs have been spent by which input using `SpentByWriter` for the DB and `MempoolSpentBy` for the mempool. Add the `spent_by` field to `TxOutput` in the protobuf; this uses the `OutPoint` message, note that this points to an input. Also add a `OutputsSpent` helper to query us the required data to tell which outputs have been spent by which tx. Depends on D13757 and D13756.
