456e350926adde5dabdbc85fc0f017fb29bdadb3 wallet: resolve ambiguity of two ScriptPubKey managers providing same script (S3RK)

Pull request description:

  This PR fixes certain use-cases when **send-to-self** transactions are missing from `listtransactions` output.

  1. When a receiving address is generated externally to the wallet
  (e.g. same wallet running on two nodes, or by 3rd party from xpub)
  2. When restoring backup with lost metadata, but keypool gap is not exceeded yet

  When the block is connected or tx added to mempool we already mark used keys. This PR extends this logic to determine whether the destination is a receiving one and if yes add it to the address book with empty label.

  Works both for legacy and descriptors wallets.
  - For legacy it uses the internal flag from the keypool entry. Caveat: because we don't know which script type would be used we add all possible destinations for such keys.
  - For descriptor wallets it uses internal flag for the script pub key manager. Caveat: it only works for active descriptors.

  fixes #19856
  fixes #20293
