[Enhancement] LMQ logic queue order maybe wrong

[redlsz]

Before Creating the Enhancement Request

• I have confirmed that this should be classified as an enhancement rather than a bug/feature.

Summary

The INNER_MULTI_QUEUE_OFFSET of LMQ messages may be not continuous. As shown in the screenshot, "1075474,1075481,1075481" is skipped. By checking the commitlog, we found that this offset is occupied by one RETRY message but is not dispatched to LMQ cq in the end.

Store error logs when this issue occurs:

Motivation

Make sure the LMQ logic queue order is correct.

Describe the Solution You'd Like

When appending commitlog, do not allocate LMQ offset for messages of system topics, be consistent with consume queue dispath logic.
