before querycoord stop gracefully, we will save the current target to
meta store and recover it after querycoord start up, to speed the
querycoord's recovery time. but the target version hasn't been recovered
as expected, and it use latest timestamp as current target's version,
which has no effect to querycoord but an unnecessary syncTargetVersion
func call.
This PR recover the correct target version to avoid unnecessary
syncTargetVersion func call

https://github.com/milvus-io/milvus/issues/35112
This pr would not affect milvus functionality by now.
It implments a Chunk memory layout that looks like
```
VariableColumn
|offset|offset|offset|
|data|data|data|
```
We maybe move offsets to the beginning and add null bitmaps later but
not in this PR.
And mmap test will also be added in another PR.

if collection's segment list doesn't changes anymore, then the next
target will be empty at most time, and balance segment will check
whether segment exist in both current and next target, so the balance
cloud be blocked due to next target is empty.
This PR permit segment to be moved if next target is empty, to avoid
balance stuck.

fix two problems:
1. count(*) incorrect, if growing insert duplicated (pk, timestamp)
pairs that pk and timestamp all same, need to keep just one pair.
2. count(*) may core dump, if get_real_count interface get snapshot and
do mvcc at not consistency status, mainly happens under concurrency.
