The new `descriptors` argument needs to be added to the Command and
ConvertParams tables to by usable as a named argument and by
bitcoin-cli.
Also update the test to use named arguments to test this.

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`).

ACK 26fe9b9, checked refactors and tests look comprehensive. Still missing a release note but can be added later.

FundTransaction calls GetMinimumFee which, when the fee rate is absurdly high, quietly reduced the fee to -maxtxfee. Becaue an absurdly high fee rate is usually the result of a fat finger, aborting seems safer behavior.
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 outputs will be filled in from the UTXO set when a descriptor
is provided to show they're segwit outputs.
c87fc71f7e Bugfix: test/functional/rpc_psbt: Correct test description comment (Luke Dashjr)
097c4aa379 Bugfix: test/functional/rpc_psbt: Remove check for specific error message that depends on uncertain assumptions (Luke Dashjr)
Pull request description:
When converttopsbt is called with a signed transaction, it either fails with "TX decode failed" if one or more inputs were segwit, or "Inputs must not have scriptSigs and scriptWitnesses" otherwise.
Since no effort is made by the test to ensure the inputs are segwit or not, avoid checking the exact message used.
The error code is still checked to ensure it is of the correct kind of failure.

Split up DecodePSBT, which both decodes base64 and then deserializes a
PartiallySignedTransaction, into two functions: DecodeBase64PSBT, which retains
the old behavior, and DecodeRawPSBT, which only performs the deserialization.
Add a test for base64 decoding failure.
0fb2e69815 CreateTransaction: Assume minimum p2sh-p2wpkh spend size for unknown change (Gregory Sanders)
b06483c96a Remove stale comment in CalculateMaximumSignedInputSize (Gregory Sanders)
Pull request description:
This is triggered anytime a fundraw type call(psbt or legacy) is used with a change output address that the wallet doesn't know how to sign for.
This regression was added in 6a34ff5335 since BnB coin selection actually cares about this.
The fix is to assume the smallest typical spend, a P2SH-P2WPKH, which is calculated using a "prototype" dummy signature flow. Future work could generalize this infrastructure to get estimated sizes of inputs for a variety of types.
I also removed a comment which I believe is stale and misleading.

6b8d86ddb8 Require a public key to be retrieved when signing a P2PKH input (Andrew Chow)
Pull request description:
If we do not have the public key for a P2PKH input, we should not continue to attempt to sign for it.
This fixes a problem where a PSBT with a P2PKH output would include invalid BIP 32 derivation paths that are missing the public key.

Added functional tests for PSBT that test the RPCs. Also added all
of the BIP 174 test vectors (except for the updater tests) in the
functional tests.
Added a Unit test for the BIP 174 updater test vector.
