Merge bitcoin/bitcoin#23662: rpc: improve getreceivedby{address,label} performance

f336ff7 rpc: avoid expensive `IsMine` calls in `GetReceived` tally (Sebastian Falbesoner)
a7b65af rpc: avoid scriptPubKey<->CTxDestination conversions in `GetReceived` tally (Sebastian Falbesoner)

Pull request description:

  The RPC calls `getreceivedbyaddress`/`getreceivedbylabel` both use the internal helper function `GetReceived` which was introduced in PR #17579 to deduplicate tallying code. For every wallet-related transaction output, the following unnecessary operations are currently performed in the tally loop, leading to a quite bad performance (as reported in #23645):
  - converting from CScript -> TxDestination (`ExtractDestination(...)`), converting from TxDestination -> CScript (`CWallet::IsMine(const CTxDestination& dest)`); this can be avoided by directly using output scripts in the search set instead of addresses (first commit)
  - checking if the iterated output script belongs to the wallet by calling `IsMine`; this can be avoided by only adding addresses to the search set which fulfil `IsMine` in the first place (second commit)

  ### Benchmark results
  The functional test [wallet_pr23662.py](https://github.com/theStack/bitcoin/blob/pr23662_benchmarks/test/functional/wallet_pr23662.py) (not part of this PR) creates transactions with 15000 different addresses:
  - 5000 outputs (500 txs with 10 outputs each) with label set, IsMine set (received)
  - 5000 outputs (500 txs with 10 outputs each) with label set, IsMine not set (sent)
  - 5000 outputs (500 txs with 10 outputs each) without label set, IsMine not set (sent)

  Then, the time is measured for calling `getreceivedbyaddress` and `getreceivedbylabel`, the latter with two variants. Results on my machine:
