Merge #19671: wallet: Remove -zapwallettxes

3340dbadd3 Remove -zapwallettxes (Andrew Chow)

Pull request description:

  It's not clear what use there is to keeping `-zapwallettxes` given that it's intended usage has been superseded by `abandontransaction`. So this removes it outright.

  Alternative to #19700

ACKs for top commit:
