Merge #16250: signrawtransactionwithkey: report error when missing redeemScript/witnessScript

01174596e6 signrawtransactionwithkey: report error when missing redeemScript/witnessScript param (Anthony Towns)

Pull request description:

  Adding support for "witnessScript" as an alternative to "redeemScript" when using "signrawtransactionwithkey" meant that the `RPCTypeCheckObj()` call in `SignTransaction` can't error out just because either parameter is missing -- it's only a problem if both are missing, which isn't a state `RPCTypeCheckObj()` tests for. This results in the regression described in #16249. This patch adds some code to test for this case and give a similar error, namely:

      error code: -8
      error message:
      Missing redeemScript/witnessScript

  Fixes: #16249
