fix(contracts): OZ-L1-L04 Lost Funds in Messenger Contracts

[zimpha]

Purpose or design rationale of this PR

This PR fix the bug (L-04 Lost Funds in Messenger Contracts) reported by OpenZeppelin. The following are the details:

The ScrollMessengerBase contract has a receive function that does not have any code implemented. There is no use case for the messenger contracts to receive any ETH outside of the payable functions. Instead, users might accidentally send ETH to it. Hence, consider removing the receive function.

The receive function is used for initialization. Adding an onlyOwner modifier to make sure no other user can send funds to the contract.
