Cherry-pick #12602

Motivation

For the non-durable cursor, the ledgers trimming task will cause skip the removed ledgers
to avoid readers introduced backlogs and make sure the data can be removed if over the retention,
more details to see #6787.

But for a topic that enabled compaction, this will lead to the reader skipping the compacted data.
The newly added test can illustrate this problem well. For reading compacted data, reading a message ID
that earlier that the first message ID of the original data is normal behavior, so we should not
move forward the cursor which will read the compacted data.
