doris/be/src/olap/tablet_schema.cpp
Xinyi Zou b34ed43ec9 [feature-wip] (memory tracker) (step6, End) Fix some details (#9301) 
1. Fix LoadTask, ChunkAllocator, TabletMeta, Brpc, the accuracy of memory track.
2. Modified some MemTracker names, deleted some unnecessary trackers, and improved readability.
3. More powerful MemTracker debugging capabilities.
4. Avoid creating TabletColumn temporary objects and improve BE startup time by 8%.
5. Fix some other details.
