array_contains_all

### description

#### Syntax

`BOOLEAN array_contains_all(ARRAY<T> array1, ARRAY<T> array2)`

check whether array1 contains the subarray array2, ensuring that the element order is exactly the same. The return results are as follows:

```
1    - array1 contains subarray array2;
0    - array1 does not contain subarray array2;
NULL - array1 or array2 is NULL.
```
