L0 segments now do not contain insert data and may cause confusion for
query hook optimizer if counted as sealed segment number.
This PR add segment level flag in segment entry and exclude L0 segments
while get readable segment snapshot

after qc restarts, and target is not ready yet, if dist_handler try to
update segment dist, it will set legacy level to l0 segment, which may
cause l0 segment be moved to other node, cause search/query failed.

Grow slice & map.growWork may cause a lot when segment number is large
for big K query. This PR pre-allocate space for reduce methods to avoid

THe querynode pipeline will make map & call ProcessInsert when there is
no write messages. So querynodes will have high CPU usage even when
there is no workload.

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.
