Describe the bug

Follow on to #6872
When I was working on #6986 I noticed the bug: when the function input are arrays with different dimensions and they are not in order, the function cannot determine the data type of the output.

To fix the bug, we should rewrite create_physical_expr for ArrayConcat built in function.

To Reproduce

# a = 2d, b = 3d, c = 1d arrays
select array_concat(a, b, c) from arrays;

Expected behavior
