correctly label witness_utxo vs non_witness_utxo key in supplementary inputs
Summary of test vector changes:
removed test:
- psbt structure: empty PSBT_OUT_SCRIPT field when sending to non-sp output
modified test:
- ecdh coverage: only one ineligible P2SH multisig input when PSBT_OUT_SCRIPT set for sp output
- can finalize: one P2PKH input single-signer
- can finalize: two inputs using per-input ECDH shares - only eligible inputs contribute shares (P2SH excluded)
added test:
- can finalize: two inputs using global ECDH share - only eligible inputs contribute shares (P2SH excluded)

Also align correctly in case of multiple authors.
Also line up with additional items in the lines below.

After the scripted changes, the changes to BIP-40, BIP-41, and BIP-63
were undone, because it breaks CI.
These three BIPs only exist conceptually and their proposal documents
are missing which causes changes to them ot break the CI. I defer the
changes to these BIPs to a separate pull request to get CI to pass.
Assuming a by one increment in the keytype of the silent payments output
fields, the following numeral to 0x09 in the hexadecimal system is 0x0a,
not 0x10.
