This PR is to make sharing hash table for broadcast more robust:
Add a session variable to enable/disable this function.
Do not block the hash join node's close function.
Use shared pointer to share hash table and runtime filter in broadcast join nodes.
The Hash join node that doesn't need to build the hash table will close the right child without reading any data(the child will close the corresponding sender).
PR https://github.com/apache/doris/pull/13917 has supported lazy read for non-predicate columns in ParquetReader,
but can't trigger lazy read when predicate columns are partition or missing columns.
This PR support such case, and fill partition and missing columns in `FileReader`.
Before this pr, if we try to load ORC file with native list(or array) type data, the be will crash.
Because complex types in ORC file include multi real columns, so we need to filter columns by column names.
Otherwise we could not read all columns we need.
Now arrow release-7.0.0 only support create stripe reader by column index, so we patch it to support create stripe reader by column names.

refractor DataTypeArray from_string, make it more clear;
support ',' and ']' inside string element, for example: ['hello,,,', 'world][]']
support empty elements, such as [,] ==> [0,0]

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.
This pr does three things：
1. Modified the framework of table-valued-function(tvf).
2. be support `fetch_table_schema` rpc.
3. Implemented `S3(path, AK, SK, format)` table-valued-function.
1. Missing field and line delimiter
2. When query external table with text(csv) format, we should pass the column position map to BE,
otherwise the column order is wrong.
TODO:
1. For now, if we query csv file with non-exist column, it will return null.
But it should return null or default value of that column.
2. Add regression test after hive docker is ready.
