feat: Defer cleanup for log/index compactions, add debug log (#26511)#26629

I believe that there is something happening which causes CurrentCompactionN() to always be greater than 0. Thus making Partition.Wait() hang forever.
Taking a look at some profiles where this issue occurs. I'm seeing a consistent one where we're stuck on Partition.Wait()

Defer'ing compaction count cleanup inside goroutines should help with any hanging current compaction counts.
Modify currentCompactionN to be a sync atomic.
Adding a debug level log within Compaction.Wait() should aid in debugging.
