chore: refactor MessagIdHook/ISM tests into a common `ExternalBridgeTest` contract (#4490)
### Description We currently have 6 different versions of ISMs derived from AbstractMessageIdAuthorizedIsm: - OPL2ToL1 - ArbL2ToL1 - OPStack (L1->L2) - ERC5164 - LayerZero - PolygonPOS But all of them have their own custom test suite right now, with widely overlapping testing areas. For standardizing the tests, I've created a base test contract `ExternalBridgeTest` that handles the common tests. This has a few benefits: - harder to miss tests for known pitfalls like msg.value or asynchronicity assumption for verifyMessageId - less code duplication with each additional Ism I have moved OPL2ToL1, ArbL2ToL1, OPStack, and ERC5164 to the new base test, and I'll forgo the rest for now because of the time sensitivity of audit remediations. I've created an issue tracking the remaining work here: https://github.com/hyperlane-xyz/issues/issues/1384 ### Drive-by changes None ### Related issues Related to https://github.com/chainlight-io/2024-08-hyperlane/issues/3 ### Backward compatibility Yes ### Testing Unitpull/4542/head
