fix: preventing original chain name & destination chain name are the same

[ahramy]

AXE-4776

• In InterchainTokenFactory.deployRemoteInterchainToken, check if destinationChain is the same as originalChainName to prevent remote deployment requests to the original chain.
• Check originalChainName and destinationChain in InterchainTokenFactory.deployRemoteCanonicalInterchainToken to ensure that a remote deploy cannot be requested to the original chain.
• Unit test coverage is 100% for InterchainTokenFactory.sol and InterchainTokenService.sol
