This cleans up the code for handling the checksig and checkmultisig opcode strict signatures to explicitly call out any semantics that are likely not obvious and improve readability. It also introduce new distinct errors for each condition which can result in a signature being rejected due to not following the strict encoding requirements and updates reference test adaptor accordingly.
