9f8de89659 [refactor](exec) replace the single pointer with an array of 'conjuncts' in ExecNode (#19758) 
Refactoring the filtering conditions in the current ExecNode from an expression tree to an array can simplify the process of adding runtime filters. It eliminates the need for complex merge operations and removes the requirement for the frontend to combine expressions into a single entity.

By representing the filtering conditions as an array, each condition can be treated individually, making it easier to add runtime filters without the need for complex merging logic. The array can store the individual conditions, and the runtime filter logic can iterate through the array to apply the filters as needed.

This refactoring simplifies the codebase, improves readability, and reduces the complexity associated with handling filtering conditions and adding runtime filters. It separates the conditions into discrete entities, enabling more straightforward manipulation and management within the execution node.

16a394da0e [chore](build) Use include-what-you-use to optimize includes (PART III) (#18958) 
Currently, there are some useless includes in the codebase. We can use a tool named include-what-you-use to optimize these includes. By using a strict include-what-you-use policy, we can get lots of benefits from it.

5a44eeaf62 [refactor] Unify all unit tests into one binary file (#8958) 
1. solved the previous delayed unit test file size is too large (1.7G+) and the unit test link time is too long problem problems
2. Unify all unit tests into one file to significantly reduce unit test execution time to less than 3 mins
3. temporarily disable stream_load_test.cpp, metrics_action_test.cpp, load_channel_mgr_test.cpp because it will re-implement part of the code and affect other tests

c5718928df [feature-wip](array-type) support explode and explode_outer table function (#8766) 
explode(ArrayColumn) desc:
> Create a row for each element in the array column. 

explode_outer(ArrayColumn) desc:
> Create a row for each element in the array column. Unlike explode, if the array is null or empty, it returns null.

Usage example:
1. create a table with array column, and insert some data;
2. open enable_lateral_view and enable_vectorized_engine;
```
set enable_lateral_view = true;
set enable_vectorized_engine=true;
```
3. use explode_outer
```
> select * from array_test;
+------+------+--------+
| k1   | k2   | k3     |
+------+------+--------+
|    3 | NULL | NULL   |
|    1 |    2 | [1, 2] |
|    2 |    3 | NULL   |
|    4 | NULL | []     |
+------+------+--------+

> select k1,explode_column from array_test LATERAL VIEW explode_outer(k3) TempExplodeView as explode_column;
+------+----------------+
| k1   | explode_column |
+------+----------------+
|    1 |              1 |
|    1 |              2 |
|    2 |           NULL |
|    4 |           NULL |
|    3 |           NULL |
+------+----------------+
```
4. explode usage example. explode return empty rows while the ARRAY is null or empty
```
> select k1,explode_column from array_test LATERAL VIEW explode(k3) TempExplodeView as explode_column;
+------+----------------+
| k1   | explode_column |
+------+----------------+
|    1 |              1 |
|    1 |              2 |
+------+----------------+
```
