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.

"-1" as `InvalidPartitionID` previously used as All partition place
holder in delete cases. It's confusing and hard to maintain when a const
var has more than one meaning.
This PR add `AllPartitionsID` to replace these usages in delete
scenarios.

when give scope CurrentTargetFirst/NextTargetFirst, it's expected to
scan both current and next target.
This PR fixed wrong behavior of CurrentTargetFirst/NextTargetFirst in
target manager, which may cause unexpected task generated, and load
collection may stuck forever due to dirty leader view.

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.
