Allow UNWIND for ARRAY data type

[prrao87]

In testing the ARRAY data type, it seems like UNWIND doesn't work for it like it does for LIST. We should support UNWIND for ARRAY too, considering it's just a special case of LIST.

kuzu> UNWIND CAST([[5,2,1],[2,3],[15,64,74]], 'INT64[][3]') AS x RETURN x;
Error: Binder exception: CAST(LIST_CREATION(LIST_CREATION(5,2,1),LIST_CREATION(2,3),LIST_CREATION(15,64,74)), INT64[][3]) has data type INT64[][3] but LIST was expected.

For LIST, this works fine:

kuzu> UNWIND [[5,2,1],[2,3],[15,64,74]] AS x RETURN x;
--------------
| x          |
--------------
| [5,2,1]    |
--------------
| [2,3]      |
--------------
| [15,64,74] |
--------------
