Merge bitcoin/bitcoin#25526: wallet: avoid double keypool TopUp() call on descriptor wallets

bfb9b94ebe wallet: remove duplicate descriptor type check in GetNewDestination (furszy)
76b982a4a5 wallet: remove unused `nAccountingEntryNumber` field (furszy)
599ff5adfc wallet: avoid double TopUp() calls on descriptor wallets (furszy)

Pull request description:

  Found it while was digging over a `getnewaddress` timeout on the functional test suite.

  ### Context:

  We are calling `TopUp()` twice in the following flows for descriptor wallets:

  A) `CWallet::GetNewDestination`:
     1) Calls spk_man->TopUp()
     2) Calls spk_man->GetNewDestination() --> which, after the basic script checks, calls TopUp() again.

  B) `CWallet::GetReservedDestination`:
     1) Calls spk_man->TopUp()
     2) Calls spk_man->GetReservedDestination() --> which calls to GetNewDestination (which calls to TopUp again).

  ### Changes:

  Move `TopUp()` responsibility from the wallet class to each scriptpubkeyman.
  So each spkm can decide to call it or not after perform the basic checks
  for the new destination request.

  Aside from that, remove the unused `nAccountingEntryNumber` wallet field. And a duplicated descriptor type check in `GetNewDestination`
