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