issue: #35821
After collection loaded, if we need to increase/decrease collection's
replica, we need to release and load it again.
milvus offers 4 solution to update loaded collection's replica, this PR
aims to dynamic change the replica number without release, and after
replica number changed, milvus will execute load replica or release
replica in async, and the replica loaded status can be checked by
getReplicas API.
Notice that if set too much replicas than querynode can afford，the new
replica won't be loaded successfully until enough querynode joins.

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.

- ReplicaManager manage read only node now, and always do persistent of
node distribution of replica.
- All segment/channel checker using ReplicaManager to get read-only node
or read-write node, but not ResourceManager.
- ReplicaManager promise that only apply unique querynode to one replica
in same collection now (replicas in same collection never hold same
querynode at same time).
- ReplicaManager promise that fairly node count assignment policy if
multi replicas of collection is assigned to one resource group.
- Move some parameters check into ReplicaManager to avoid data race.
- Allow transfer replica to resource group that already load replica of
same collection
- Allow transfer node between resource groups that load replica of same
collection

When colleciton number is large, querycoord saves collection target one
by one, which is slow and may block querycoord exits.
In local run, 500 collections scenario may lead to about 40 seconds
saving collection targets.
This PR changes the `SaveCollectionTarget` interface into batch one and
organizes the collection in 16 per bundle batches to accelerate this
procedure.

issue: #28491
after querycoord restart, it will pull a new target, which include
channel and segment list. when segments loaded on querynode has reached
the target, the collection could provide search/query. but if segment
list changes by time, ater querycoord pull a new target, it will takes a
few minutes to catch up the target's segment distribution. and before
that, query/search will fail due to lack of segments.
This PR save the current loaded target to meta storein querycoord's stop
progress, and recover it when query coord starts, to speed up the target
recovery time.

This PR includes the following adjustments:
1. To prevent channelCP update task backlog, only one task with the same
vchannel is retained in the updater. Additionally, the lastUpdateTime is
refreshed after the flowgraph submits the update task, rather than in
the callBack function.
2. Batch updates of multiple vchannel checkpoints are performed in the
UpdateChannelCheckpoint RPC (default batch size is 128). Additionally,
the lock for channelCPs in DataCoord meta has been switched from key
lock to global lock.
3. The concurrency of UpdateChannelCheckpoint RPCs in the datanode has
been reduced from 1000 to 10.
