fix: call injectDone after compaction failed (#30277)
syncMgr.Block() will lock the segment when executing compaction.

Previous implementation was unable to Unblock thoese segments when
compaction failed. If next compaction of the same segments arrives,
it'll stuck forever and block all later compation tasks.

This PR makes sure compaction executor would Unblock these segments
after a failure compaction.

Apart form that, this PR also refines some logs and clean some codes of
compaction, compactor:

1. Log segment count instead of segmentIDs to avoid logging too many
segments
2. Flush RPC returns L1 segments only, skip L0 and L2
3. CompactionType is checked in `Compaction`, no need to check again
inside compactor
4. Use ligter method to replace `getSegmentMeta`
5. Log information for L0 compaction when encounters an error
