1. gorwing L0 segments is invisible to datacoord.
2. flushed L0 segments need to clean by datacoord.

Due to the removal of injection and syncSegments from the compaction, we
need to ensure that no compaction is successfully executed during the
rolling upgrade. This PR renames Compaction to CompactionV2, with the
following effects:
- New datacoord + old datanode: Utilizes the CompactionV2 interface,
resulting in the datanode error "CompactionV2 not implemented," causing
compaction to fail;
- Old datacoord + new datanode: Utilizes the CompactionV1 interface,
resulting in the datanode error "CompactionV1 not implemented," causing
compaction to fail.

The data coordinator computed the appropriate number of import segments,
thus when importing in the data node, one can randomly select a segment.

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"}
- Basic BF TestLocation cost {"time": "3.197430181s"}

`LocationCache` used map to store different locations for different K
which may cause lots of CPU time when get locations many times.
This PR change the implementation of LocationCache to store only the
location for the largest K used to totally remove the map access
operation.

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

Avoid passing datanode around preparing datanode code directory
refactory.
Also refine unit test code for same component. The `Await` shall return
first before checking the counter number since when lock cost is heavy
(using deadlock.RWMutex See PR #33069.) case may fail due to long
running time submitting tasks.

1. add `MemorySize` field for insert binlog.
2. `LogSize` means the file size in the storage object.
3. `MemorySize` means the size of the data in the memory.
