Cherry-pick #12698
### Motivation
Fix lost compaction data due to compaction properties missed during
reset-cursor.
1. The compaction reader will seek to the earliest position to read data
from the topic, but the compaction properties missed during the cursor reset,
this will lead to the inited compaction subscribe without compaction horizon,
so the compaction reader will skip the last compacted data. It will only happen
when init the compaction subscription, so can introduced by the loadbalance or
topic unloading manually.
2. Advance the cursor should also keep the properties, otherwise, the
properties will lost during the cursor trimming.
### Changes
1. Keep the properties for resetting the cursor while the cursor is for data
compaction.
2. Copy the properties to the new mark delete entry while advance the
cursor, this is triggered byt the managed ledger internal, so it's not only for
compacted topic, the internal task should not loss the properties when trimming
the cursor.
### Tests
New tests added to make sure the compaction will not loss data during topic
unloading and the reader can read all the compacted data after the compaction
task complete
