Merge bitcoin/bitcoin#25122: rpc: getreceivedbylabel, return early if no addresses were found in the address book

baa3ddc49c46d00e3e0de06e494656f0f00b0ee8 doc: add release notes about `getreceivedbylabel` returning an error if the label is not in the address book. (furszy)
8897a21658ad93f7b628eb2a3411fec2265d73fb rpc: getreceivedbylabel, don't loop over the entire wallet txs map if no destinations were found for the input label. (furszy)

Pull request description:

  Built on top of #23662, coming from comment https://github.com/bitcoin/bitcoin/pull/23662#pullrequestreview-971407999.

  If `wallet.GetLabelAddresses()` returns an empty vector (the wallet does not have stored destinations with that label in the addressbook) or if none of the returned destinations are from the wallet, we can return the function right away.
  Otherwise, we are walking through all the wallet txs + outputs for no reason (`output_scripts` is empty).
