Merge #17371: Refactor: Require scriptPubKey to get wallet SigningProvider

Browse Source 
d0dab897af Refactor: Require scriptPubKey to get wallet SigningProvider (Andrew Chow)
4b0c718f8f Accumulate result UniValue in SignTransaction (Andrew Chow)

Pull request description:

  Easier to review ignoring whitespace:

      git log -p -n1 -w

  This commit does not change behavior. It passes new CScript arguments to
  signing functions, but the arguments aren't currently used.

  Split from #17261
