Xinyi Zou 0b945fe361 [enhancement](memtracker) Refactor mem tracker hierarchy (#13585) 
mem tracker can be logically divided into 4 layers: 1)process 2)type 3)query/load/compation task etc. 4)exec node etc.

type includes

enum Type {
        GLOBAL = 0,        // Life cycle is the same as the process, e.g. Cache and default Orphan
        QUERY = 1,         // Count the memory consumption of all Query tasks.
        LOAD = 2,          // Count the memory consumption of all Load tasks.
        COMPACTION = 3,    // Count the memory consumption of all Base and Cumulative tasks.
        SCHEMA_CHANGE = 4, // Count the memory consumption of all SchemaChange tasks.
        CLONE = 5, // Count the memory consumption of all EngineCloneTask. Note: Memory that does not contain make/release snapshots.
        BATCHLOAD = 6,  // Count the memory consumption of all EngineBatchLoadTask.
        CONSISTENCY = 7 // Count the memory consumption of all EngineChecksumTask.
    }
Object pointers are no longer saved between each layer, and the values of process and each type are periodically aggregated.

other fix:

In [fix](memtracker) Fix transmit_tracker null pointer because phamp is not thread safe #13528, I tried to separate the memory that was manually abandoned in the query from the orphan mem tracker. But in the actual test, the accuracy of this part of the memory cannot be guaranteed, so put it back to the orphan mem tracker again.
