26fe9b9909 Add support for descriptors to utxoupdatepsbt (Pieter Wuille)
3135c1a2d2 Abstract out UpdatePSBTOutput from FillPSBT (Pieter Wuille)
fb90ec3c33 Abstract out EvalDescriptorStringOrObject from scantxoutset (Pieter Wuille)
eaf4f88734 Abstract out IsSegWitOutput from utxoupdatepsbt (Pieter Wuille)

Pull request description:

  This adds a descriptors argument to the `utxoupdatepsbt` RPC. This means:
  * Input and output scripts and keys will be filled in when known.
  * P2SH-witness inputs will be filled in from the UTXO set when a descriptor is provided that shows they're spending segwit outputs.

  This also moves some (newly) shared code to separate functions: `UpdatePSBTOutput` (an analogue to `SignPSBTInput`), `IsSegWitOutput`, and `EvalDescriptorStringOrObject` (implementing the string or object notation parsing used in `scantxoutset`).
