e412dd12e8 [chore](build) Use include-what-you-use to optimize includes (PART II) (#18761)
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.

4d516bece8 [feature-wip](array-type)Add element_at and subscript functions (#8597)
Describe the overview of changes.
1. add function element_at;
2. support element_subscript([]) to get element of array, col_array[N] <==> element_at(col_array, N);
3. return error message instead of BE crash while array function execute failed;

element_at(array, index) desc:
>   Returns element of array at given **(1-based)** index. 
  If **index < 0**, accesses elements from the last to the first. 
  Returns NULL if the index exceeds the length of the array or the array is NULL.

Usage example:
1. create table with ARRAY type column and insert some data:
```
+------+------+--------+
| k1   | k2   | k3     |
+------+------+--------+
|    1 |    2 | [1, 2] |
|    2 |    3 | NULL   |
|    4 | NULL | []     |
|    3 | NULL | NULL   |
+------+------+--------+
```
2. enable vectorized:
```
set enable_vectorized_engine=true;
```
3. element_subscript([]) usage example:
```
> select k1,k3,k3[1] from array_test;
+------+--------+----------------------------+
| k1   | k3     | %element_extract%(`k3`, 1) |
+------+--------+----------------------------+
|    3 | NULL   |                       NULL |
|    1 | [1, 2] |                          1 |
|    2 | NULL   |                       NULL |
|    4 | []     |                       NULL |
+------+--------+----------------------------+
```
4. element_at function usage example:
```
> select k1,k3 from array_test where element_at(k3, -1) = 2;
+------+--------+
| k1   | k3     |
+------+--------+
|    1 | [1, 2] |
+------+--------+
```

## 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
