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 |
+------+----------------+
```

71ce3c4a6e [feature-wip](array-type) Add codes and UT for array_contains and array_position functions (#8401) (#8589) 
array_contains function Usage example:
1. create table with ARRAY column, and insert some data:
```
> select * from array_test;
+------+------+--------+
| k1   | k2   | k3     |
+------+------+--------+
|    1 |    2 | [1, 2] |
|    2 |    3 | NULL   |
|    4 | NULL | []     |
|    3 | NULL | NULL   |
+------+------+--------+
```
2. enable vectorized:
```
> set enable_vectorized_engine=true;
```
3. select with array_contains:
```
> select k1,array_contains(k3,1) from array_test;
+------+-------------------------+
| k1   | array_contains(`k3`, 1) |
+------+-------------------------+
|    3 |                    NULL |
|    1 |                       1 |
|    2 |                    NULL |
|    4 |                       0 |
+------+-------------------------+
```
4. also we can use array_contains in where condition
```
> select * from array_test where array_contains(k3,1);
+------+------+--------+
| k1   | k2   | k3     |
+------+------+--------+
|    1 |    2 | [1, 2] |
+------+------+--------+
```
5. array_position usage example
```
> select k1,k3,array_position(k3,2) from array_test;
+------+--------+-------------------------+
| k1   | k3     | array_position(`k3`, 2) |
+------+--------+-------------------------+
|    3 | NULL   |                    NULL |
|    1 | [1, 2] |                       2 |
|    2 | NULL   |                    NULL |
|    4 | []     |                       0 |
+------+--------+-------------------------+
```

## Problem Summary:

### 1. Some code from clickhouse

**ClickHouse is an excellent implementation of the vectorized execution engine database,
so here we have referenced and learned a lot from its excellent implementation in terms of
data structure and function implementation.
We are based on ClickHouse v19.16.2.2 and would like to thank the ClickHouse community and developers.**

The following comment has been added to the code from Clickhouse, eg:
// This file is copied from
// https://github.com/ClickHouse/ClickHouse/blob/master/src/Interpreters/AggregationCommon.h
// and modified by Doris

### 2. Support exec node and query:
* vaggregation_node
* vanalytic_eval_node
* vassert_num_rows_node
* vblocking_join_node
* vcross_join_node
* vempty_set_node
* ves_http_scan_node
* vexcept_node
* vexchange_node
* vintersect_node
* vmysql_scan_node
* vodbc_scan_node
* volap_scan_node
* vrepeat_node
* vschema_scan_node
* vselect_node
* vset_operation_node
* vsort_node
* vunion_node
* vhash_join_node

You can run exec engine of SSB/TPCH and 70% TPCDS stand query test set.

### 3. Data Model

Vec Exec Engine Support **Dup/Agg/Unq** table, Support Block Reader Vectorized.
Segment Vec is working in process.

### 4. How to use

1. Set the environment variable `set enable_vectorized_engine = true; `(required)
2. Set the environment variable `set batch_size = 4096; ` (recommended)

### 5. Some diff from origin exec engine

2. Has unit tests been added: (Yes)
3. Has document been added or modified: (No)
4. Does it need to update dependencies: (No)
