Pull request description:

  Currently, we do not add the sighash field to PSBTs at all, even when we have signed with a non-default sighash. This PR changes the behavior such that when we (attempt to) sign with a sighash other than DEFAULT or ALL, the sighash type field will be added to the PSBT to inform the later signers that a different sighash type was used by a signer. Notably, this is necessary for MuSig2 support as all signers must sign using the same sighash type, but the sighash is not provided in partial signatures.

  Furthermore, because the sighash type can also be provided on the command line, we require that if both a command line sighash type and the sighash field is present, they must specify the same sighash type. However, this was being checked by the wallet, rather than the signing code, so the `descriptorprocesspsbt` RPC was not enforcing this restriction at all, and in fact ignored the sighash field entirely. This PR refactors the checking code so that the underlying PSBT signing function `SignPSBTInput` does the check.

src/node/

The src/node/ directory contains code that needs to access node state (state in CChain, CBlockIndex, CCoinsView, CTxMemPool, and similar classes).

Code in src/node/ is meant to be segregated from code in src/wallet/ and src/qt/, to ensure wallet and GUI code changes don't interfere with node operation, to allow wallet and GUI code to run in separate processes, and to perhaps eventually allow wallet and GUI code to be maintained in separate source repositories.

As a rule of thumb, code in one of the src/node/, src/wallet/, or src/qt/ directories should avoid calling code in the other directories directly, and only invoke it indirectly through the more limited src/interfaces/ classes.

This directory is at the moment sparsely populated. Eventually more substantial files like src/validation.cpp and src/txmempool.cpp might be moved there.
