Pull request description:
Implements the changes to BIP 174 proposed in https://github.com/bitcoin/bips/pull/849 and https://github.com/bitcoin/bips/pull/784
Implements `PSBT_GLOBAL_VERSION`, `PSBT_GLOBAL_PROPRIETARY`, `PSBT_IN_PROPRIETARY`, `PSBT_OUT_PROPRIETARY`, and `PSBT_GLOBAL_XPUB`. The `PSBT_GLOBAL_XPUB` changes are merged in from #16463.
Also includes the test vectors added to BIP 174 for these fields.
A number of additional changes to keypath and xpub serialization are made to support `PSBT_GLOBAL_XPUB`.
