Runtime: avoid duplication and test all signature

[ashWhiteHat]

Description

I found signature test code following duplication. https://github.com/paritytech/substrate/blob/fbdf00888d778bab4d31a8938de7bed7e53d2d53/primitives/runtime/src/traits.rs#L2424-L2425

ecdsa error case is not tested and ed25519/sr25519 cases are not tested. I added following test cases

• ecdsa error
• ed25519 normal/error
• sr25519 normal/error
• bls377 normal/error
• bls381 normal/error
