This pull request introduces several changes across multiple files. Here is a summary of the diff:

1. In the file benchmark_state_test.go, a slice of uint8 is modified to generate a random value using the rand.Intn function, preventing duplicate keys.
2. In the file persistence_module.go, new methods SetIBCEvent and GetIBCEvents are added to enhance the persistence module's functionality for handling IBC events.
3. In a different file related to IBC functionality, imports are added, and new methods SetIBCEvent and GetIBCEvents are added for storing and retrieving IBC events at a specific height and topic.
4. In the file persistence/types/ibc.go, multiple changes include adding constants, new functions for generating queries, renaming a function, and modifying existing functions for handling IBC events and entries.
5. In the file bus.go, a new function GetEventLogger is added to the bus struct, returning a value of type modules.EventLogger.
6. Another file diff involves adding imports, initializing variables related to the IBC submodule, and updating the Create() function in the ibc/host package.
7. In ibc_test.go, there are modifications to test functions, adding new test functions, and adding an attribute struct.
8. A new file ibc_event_module.go is added, defining a package, imports, constants, types, and methods related to an event logging system.
9. Changes in bus_module.go show the addition of a new method GetEventLogger to the Bus interface.
10. In persistence/debug.go, functions ClearAllIBCQuery, ClearAllIBCStoreQuery, and ClearAllIBCEventsQuery are added/removed, and a modification is made to the HandleDebugMessage function signature.
11. A new file event_manager.go is added, containing the definition of the EventManager struct and implementing the EventLogger interface.
12. A change is made to add a new table creation statement for the IBCEventLog table in an unspecified file.
13. Changes in the file ics24.md introduce a new section for an event logging system in the IBC module, with an overview of its implementation and usage of a persistence layer.
14. A new file ibc_events.proto is added, defining message types for attributes and IBC events in the shared/core/types/proto directory.

These changes aim to introduce and enhance functionality related to IBC events, event logging, and persistence in the project.
