DorianZheng 27090ae8f6 Fix DBImpl::GetColumnFamilyHandleUnlocked race condition (#4391) 
Summary:
- Fix DBImpl API race condition

The timeline of execution flow is as follow:
```
timeline              user_thread1                      user_thread2
t1   |     cfh = GetColumnFamilyHandleUnlocked(0)
t2   |     id1 = cfh->GetID()
t3   |                                                GetColumnFamilyHandleUnlocked(1)
t4   |     id2 = cfh->GetID()
     V
```
The original implementation return a pointer to a stateful variable, so that the return `ColumnFamilyHandle` will be changed when another thread calls `GetColumnFamilyHandleUnlocked` with different `column family id`

- Expose ColumnFamily ID to compaction event listener

- Fix the return status of `DBImpl::GetLatestSequenceForKey`
