Merge bitcoin/bitcoin#22650: Remove -deprecatedrpc=addresses flag and corresponding code/logic

43cd6b8af9 doc: add release notes for removal of the -deprecatedrpc=addresses flag (Michael Dietz)
2b1fdc2c6c refactor: minor styling, prefer snake case and same line if (Michael Dietz)
d64deac7b8 refactor: share logic between ScriptPubKeyToUniv and ScriptToUniv (Michael Dietz)
8721638daa rpc: remove deprecated addresses and reqSigs from rpc outputs (Michael Dietz)

Pull request description:

  Resolves #21797 now that we've branched-off to v23 ("addresses" and "reqSigs" deprecated) "ExtractDestinations" should be removed.

   `-deprecatedrpc=addresses` was initially added in this PR #20286 (which resolved the original issue #20102).

  Some chunks of code and logic are no longer used/necessary with the removal of this, and therefore some minor refactoring is done in this PR as well (separated commits)
