storage for handling with VectorArray.
This PR:
1. impls the go part of storage for VectorArray
2. impls the collection creation with StructArrayField and VectorArray
3. insert and retrieve data from the collection.

Previous code uses diskSegmentMaxSize if and only if all of the
collection's vector fields are indexed with DiskANN index.
When introducing sparse vectors, since sparse vector cannot be indexed
with DiskANN index, collections with both dense and sparse vectors will
use maxSize instead.
This PR changes the requirments of using diskSegmentMaxSize to all dense
vectors are indexed with DiskANN indexs, ignoring sparse vector fields.

This PR moves the deltalog file count check inside hasTooManyDeletions
check. Unifies the logic on checking if a segment has too many deletions
including: delta log count, deleted rows ratio and deltalog size.
This change removes several uncessary traverse through segment's binlogs
and deltalogs. And add more clear trigger logs

With concurrenct L0 compaction
(https://github.com/milvus-io/milvus/pull/36816), delta logs might be
written to the same L1 segment, causing logID duplication when using the
incremental beginLogID. This PR removes the beginLogID mechanism and
instead passes a log ID range, where the number of IDs in the range
equals the number of compaction segment binlogs multiplied by an
expansion factor.

This pr will remove pre-marking segments as L2 during clustering
compaction in version 2.5, and ensure compatibility with version 2.4.
The core of this change is to **ensure that the many-to-many lineage
derivation logic is correct, making sure that both the parent and child
cannot simultaneously exist in the target segment view.**
feature:
- Clustering compaction no longer marks the input segments as L2.
- Add a new field `is_invisible` to `segmentInfo`, and mark segments
that have completed clustering but have not yet built indexes as
`is_invisible` to prevent them from being loaded prematurely."
- Do not mark the input segment as `Dropped` before the clustering
compaction is completed.
- After compaction fails, only the result segment needs to be marked as
Dropped.
compatibility:
- If the upgraded task has not failed, there are no compatibility
issues.
- If the status after the upgrade is `MetaSaved`, then skip the stats
task based on whether TmpSegments is empty.
- If the failure occurs before `MetaSaved`:
- there are no ResultSegments, and InputSegments have not been marked as
dropped yet.
- the level of input segments need to revert to LastLevel
- If the failure occurs after `MetaSaved`:
- ResultSegments have already been generated, and InputSegments have
been marked as Dropped. At this point, simply make the ResultSegments
visible.
- the level of ResultSegments needs to be set to L1（in order to
participate in mixCompaction）

This PR includes the following changes:
1. Added a new task type to the task scheduler in datacoord: stats task,
which sorts segments by primary key.
2. Implemented segment sorting in indexnode.
3. Added a new field `FieldStatsLog` to SegmentInfo to store token index
information.
