Replace the payload parameter with message

function depositAndCall(address receiver, bytes calldata payload) external payable {

We have "payload" in the depositAndCall and "message" in the onCrossChainCall. For consistency, we should use the same name.

I think the reasoning of using payload in depositAndCall was to differentiate from message in withdrawAndCall to highlight the difference that withdrawAndCall enable a arbitrary smart contract call while for the payload we call onCrossChainCall
And we inadvertently used message in onCrossChainCall

I think it makes sense to continue on this choice and call it payload in onCrossChainCall

Hm, but it's also very intuitive that messages are being sent to universal contracts, and from universal contracts to contracts on connected chains.
