* add proto for allowed sdk denoms -> evm conversion * add validation for AllowedNativeCoinERC20Token * add validation for AllowedNativeCoinERC20Tokens * add AllowedNativeDenoms into params & genesis * add evmutil Params.Validate() test * fix eip712 ante test * update changelog * update internal testnet genesis.json * update state & param specs updates to the sections describing functionality will be updated once that functionality actually exists... :) * update field decimal -> decimals field now matches erc20 spec * add validation decimals will cast to uint8 * add v2 store migration for evmutil * create & register evmutil migrations * adds migrator to evmutil's keeper * sets up Migrate1To2 migration * registers migration in module * updates GetParams to properly handle historic block queries * add unit test for GetParams with historic store
