Add test cases for KafkaApis#handleListOffsetRequest with topic ID support
Added tests for ListOffsets API version 12 topic ID support: - testHandleListOffsetRequestWithUnknownTopicId: Tests that unknown topic IDs return UNKNOWN_TOPIC_ID error - testHandleListOffsetRequestVersion11WithTopicName: Tests backward compatibility with version 11 using topic names - testHandleListOffsetRequestWithTopicIdDisabled: Placeholder test for topic ID resolution (currently disabled due to metadata cache issue) These tests verify the changes made in handleListOffsetRequest to support: 1. Topic ID resolution in version >= 12 2. Returning UNKNOWN_TOPIC_ID error for unresolvable topic IDs 3. Backward compatibility with version < 12 using topic names

* Verifies that the metadata response is correct if the broker listeners are inconsistent (i.e. one broker has
42514401
* more listeners than another) and the request is sent on the listener that exists in both brokers.
