1. Fix Lru Cache MemTracker consumption value is negative.
2. Fix compaction Cache MemTracker has no track.
3. Add USE_MEM_TRACKER compile option.
4. Make sure the malloc/free hook is not stopped at any time.
* [Refactor][Bug-Fix][Load Vec] Refactor code of basescanner and vjson/vparquet/vbroker scanner
1. fix bug of vjson scanner not support `range_from_file_path`
2. fix bug of vjson/vbrocker scanner core dump by src/dest slot nullable is different
3. fix bug of vparquest filter_block reference of column in not 1
4. refactor code to simple all the code
It only changed vectorized load, not original row based load.

Hive and trino/presto would automatically trim the trailing spaces but Doris doesn't.
This would cause different query result with hive.
Add a new session variable "trim_tailing_spaces_for_external_table_query".
If set to true, when reading csv from broker scan node, it will trim the tailing space of the column
PaloExternalSourcesService is designed for es_scan_node using tcp protocol.
But es tcp protocol need deploy a tcp jar into es code. Both es version and lucene version are upgraded,
and the tcp jar is not maintained any more.
So that I remove all the related code and thrift definitions.
This patch supports utf8mb4 for mysql external table.
if someone needs a mysql external table with utf8mb4 charset, but only support charset utf8 right now.
When create mysql external table, it can add an optional propertiy "charset" which can set character fom mysql connection,
default value is "utf8". You can set "utf8mb4" instead of "utf8" when you need.
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.
1. fix track bthread
- Bthread, a high performance M:N thread library used by brpc. In Doris, a brpc server response runs on one bthread, possibly on multiple pthreads. Currently, MemTracker consumption relies on pthread local variables (TLS).
- This caused pthread TLS MemTracker confusion when switching pthread TLS MemTracker in brpc server response. So replacing pthread TLS with bthread TLS in the brpc server response saves the MemTracker.
Ref: 731730da85/docs/en/server.md (bthread-local)
2. fix track vectorized query
- Added track mmap. Currently, mmap allocates memory in many places of the vectorized execution engine.
- Refactored ThreadContext to avoid dependency conflicts and make it easier to debug.
- Fix some bugs.
- Add two new types to stream load boker load: **csv_with_names** and **csv_with_name_sand_types**
- Add two new types to export: **csv_with_names** and **csv_with_names_and_types**
This reverts commit de7dce4df84fcbfbbaf715cbac151e802321f80f.

This cause BE ut failed: sh run-be-ut.sh --run --filter OlapTableSinkTest.*

Currently, there are 2 status code in BE, one is common/Status.h,
and the other is olap/olap_define.h called OLAPStatus.
OLAPStatus is just an enum type, it is very simple and could not save many informations,
I will unify these code to common/Status.
We can not shutdown _send_batch_thread_pool_token, because _packet_in_flight
has to be clear finally. Otherwise a never ended join on rpc would happen.
It is difficult to handle concurrent problem if a flag setter is not guaranteed to run.
1.Member functions defined in a class are inline by default (implicitly), and do not need to be added
2.inline is a keyword used for implementation, which has no effect when placed before the function declaration
