Merge #14481: Add P2SH-P2WSH support to listunspent RPC

Browse Source 
6ca836ab3a Add release note for listunspent P2WSH change (MeshCollider)
928beae007 Add test for P2SH-P2WSH in signrawtransactionwithkey and listunspent (MeshCollider)
314784a60f Make listunspent and signrawtransaction RPCs support witnessScript (MeshCollider)

Pull request description:

  This is a reworked version of #11708 after #12427 and the `signrawtransaction` split.

  For a P2WSH address, listunspent should return the witness script, and for a P2SH-P2WSH address, it should also return the inner witness script (because SignTransaction will automatically wrap it in P2SH if required).

  Includes a test which also tests the behaviour of #12427, and release note.
