add ResolveMultisigPubKey to match a multisig signature to its pubkey

Walks sig.Pubkeys and tries ECDSA verify with each one against the
given digest. Sets and returns the matched pubkey, or nil if none
verifies. Lets callers identify the actual signer in a P2SH-multisig
spend without re-implementing the verification loop.
