enhance: refactor the drop collection and drop partition

[chyezh]

issue: #36858
pr: #37176

• Remove DropVirtualChannel when DropCollection from datanode and deprecate the rpc.
• Add DropCollection and DropPartition rpc for datacoord, and call it with stepTask when DropCollection and DropPartition happens.
• Add CollectionTombstone at datacoord to store the tombstone of collection or partition.
• Segment Meta modification will check the tombstone of collection or partition that segment belongs to before the modification to avoid resource leak when the collection or partition is dropped.
