feat: Write a zetatokenconsumer for zevm

[andresaiello]

Summary

• ZetaConsumer for ZEVM

[fadeev]

Would we be able to use the consumer on ZetaChain the same way as on Ethereum, for example?

Would this work on ZetaChain?

import "@zetachain/protocol-contracts/contracts/evm/interfaces/ZetaInterfaces.sol";

contract CrossChainMessage is ZetaInteractor, ZetaReceiver {
    ZetaTokenConsumer private immutable _zetaConsumer;

    constructor(address connectorAddress, address zetaTokenAddress, address zetaConsumerAddress) ZetaInteractor(connectorAddress) {
        _zetaToken = IERC20(zetaTokenAddress);
        _zetaConsumer = ZetaTokenConsumer(zetaConsumerAddress);
    }

    function sendMessage(uint256 destinationChainId, string memory message) external payable {
        uint256 crossChainGas = 2 * (10 ** 18);
        uint256 zetaValueAndGas = _zetaConsumer.getZetaFromEth{
            value: msg.value
        }(address(this), crossChainGas);
        _zetaToken.approve(address(connector), zetaValueAndGas);

        connector.send(...)
    }
    //...
}
