[enhancement](array-type) Split Array Offsets and String Offsets ( #12341 )
...
In old Doris version string offsets are 32bit, but it is not enough for Array type.
If we change string offsets from 32bit to 64bit, there will be problem if we upgrade BE one by one. Because at the same time 32bit Offsets and 64 bit Offsets String will exist at the same time.
As a result, we separate the Codes for Array Offsets.

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

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