Merge #13786: refactor: Avoid locking tx pool cs thrice

fa5ed4f8d2 refactor: Avoid locking tx pool cs thrice (MarcoFalke)

Pull request description:

  `addUnchecked` is (outside the tests) only called by ATMP, which already takes the tx pool read lock. So locking it twice more in both `addUnchecked` methods seems redundant.

  Similarly `CalculateMemPoolAncestors` is (beside once in the wallet) only called in contexts, where the tx pool lock is already taken. So remove the lock there as well.
