[improve][broker] Add annotation for topic compaction strategy (#20858)
### Motivation
Add `Audience.Private` annotation for topic compaction strategy. Since this interface only uses for load manager, other users should not use this interface.
(cherry picked from commit e55ed58eed4380b463d04b76dbb953d7a0ac795d)
