To speed up the construction and querying of Bloom filters, we chose a
blocked Bloom filter instead of a basic Bloom filter implementation.
WARN: This PR is compatible with old version bf impl, but if fall back
to old milvus version, it may causes bloom filter deserialize failed.
In single Bloom filter test cases with a capacity of 1,000,000 and a
false positive rate (FPR) of 0.001, the blocked Bloom filter is 5 times
faster than the basic Bloom filter in both querying and construction, at
the cost of a 30% increase in memory usage.
- Block BF construct time {"time": "54.128131ms"}
- Block BF size {"size": 3021578}
- Block BF Test cost {"time": "55.407352ms"}
- Basic BF construct time {"time": "210.262183ms"}
- Basic BF size {"size": 2396308}
- Basic BF Test cost {"time": "192.596229ms"}
In multi Bloom filter test cases with a capacity of 100,000, an FPR of
0.001, and 100 Bloom filters, we reuse the primary key locations for all
Bloom filters to avoid repeated hash computations. As a result, the
blocked Bloom filter is also 5 times faster than the basic Bloom filter
in querying.
- Block BF TestLocation cost {"time": "529.97183ms"}

There were some frequent scan in metacache:
- List all segments whose start positions not synced
- List compacted segments
Those scan shall cause lots of CPU time when flushed segment number is
large meanwhile `Flushed` segments can be skipped in those two scenarios
This PR make:
- Add segment state shortcut in metacache
- List start positions state before `Flushed`
- Make compacted segments state to be `Dropped` and use `Dropped` state
while scanning them

For a sync task, the segment could be compacted during sync task. In
previous implementation, this sync task will hold only the old segment
id as KeyLock, in which case compaction on compacted to segment may run
in parallel with delta sync of this sync task.
This PR introduces sync target segment verification logic. It shall
check target segment lock it's holding beforing actually syncing logic.
If this check failed, sync task shall return`errTargetSegementNotMatch`
error and make manager re-fetch the current target segment id.
