native: extend CryptoLib's verifyWithECDsa with hasher parameter

Browse source 
Replace native CryptoLib's verifyWithECDsa `curve` parameter by
`curveHash` parameter which is a enum over supported pairs of named
curves and hash functions.

Even though this change is a compatible extension of the protocol, it
changes the genesis state due to parameter renaming. But we're going to
resync chain in 3.7 release anyway, so it's not a big deal.

Also, we need to check mainnet and testnet compatibility in case if
anyone has ever called verifyWithECDsa with 24 or 25 `curve` value.
