Lee	ae0990a0b3	LayerZero Hook and ISM (#3102) ... ### Description - Implements LayerZero V1 and V2 hook with V2 ISM. - V2 ISM is backwards compatible i.e., V1 hook (which uses V1 endpoint to send) can send to V2 ISM (which uses V2 endpoint to receive). See [here](https://docs.layerzero.network/explore/migration#configuring-ultralightnode301) for configuration. - V2 uses `AbstractsMessageIdAuthorized*`. In. other words, hook passes messageId through LayerZero, which stores into ISM to be used when relayer calls `verify()` . - Includes unit test for both V1 and V2 hook and ISM. - V1 uses official LayerZero endpoint mock. ### Drive-by changes <!-- Are there any minor or drive-by changes also included? --> ### Related issues - Implements #2853 ### Backward compatibility Yes ### Testing Manual/Unit Tests	9 months ago
