This PR:
- Add `lock.RWMutex` & `lock.Mutex` alias to switch implementation based
on build flags
- When build flags has `test` in it, use `go-deadlock` to detect
possible deadlocks
- Replace all `sync.RWMutex` & `sync.Mutex` in datacoord pkg

Trigger l0 compaction when l0 views don't change
So that leftover l0 segments would be compacted in the end.
1. Refresh LevelZero plans in comactionPlanHandler, remove the meta
dependency
of compaction trigger v2
2. Add ForceTrigger method for CompactionView interface
3. rename mu to taskGuard
4. Add a new TriggerTypeLevelZeroViewIDLE
5. Add an idleTicker for compaction view manager

If DC restarted, those unkonwn compaction tasks
will never get call back in DN, so that the segments in the compaction
task will be locked, unable to sync and compaction again, blocking cp
advance and compaction executing.

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

This PR:
- Separates compaction scheduler and check results loop So that slow in
check-loop doesn't influence execution.
- Cleans compaction tasks when drop a vchannel so dropped-channel's
compaction tasks won't be checked over and over again.
- Skips meta change when meta's already changed, avoid panic
- Remove not inuse injectDone(bool) parameter

number in plan results and refactor some names for readibility.
