[2010YOUY01]

Which issue does this PR close?

• Closes #.

Rationale for this change

See reproducer in datafusion-cli, now array_distance() allows nested list as input, and it will use the 1st inner array to compute the distance.

> select array_distance([[1, 2], [100, 100]], [[1, 4], [0, 0]]);
+---------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| array_distance(make_array(make_array(Int64(1),Int64(2)),make_array(Int64(100),Int64(100))),make_array(make_array(Int64(1),Int64(4)),make_array(Int64(0),Int64(0)))) |
+---------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| 2.0                                                                                                                                                                 |
