Also covering SIGHASH_ANYPREVOUT

SIGHASH_NOINPUT and SIGHASH_ANYPREVOUT are proposals for a signature hash (sighash) where the identifier for the UTXO being spent is not signed, allowing the signature to be used with any UTXO that’s protected by a similar script (i.e. uses the same public keys).

A noinput-style sighash is necessary for the proposed eltoo layer for LN.
