[GitHub] [pulsar] Technoboy- opened a new pull request, #16403: [Branch-2.7][Cherry-pick] Do not move the non-durable cursor position when trimming ledgers while topic with compaction

Technoboy- opened a new pull request, #16403:
URL: https://github.com/apache/pulsar/pull/16403

   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.
