Describe the bug

In case of array_repeat, when the count variable is not of type Int64, it gives error.

In case of Int32, Int16, Int8, we should automatically convert it into Int64.

To Reproduce

select array_repeat(1 ,arrow_cast(2,'Int32'));

getting error:

Internal error: could not cast value to arrow_array::array::primitive_array::PrimitiveArray<arrow_array::types::Int64Type>.
This was likely caused by a bug in DataFusion's code and we would welcome that you file an bug report in our issue tracker

Expected behavior

select array_repeat(1,2);
+---------------------------------+
| array_repeat(Int64(1),Int64(2)) |
+---------------------------------+
| [1, 1] |
+---------------------------------+
1 row(s) fetched.

Additional context

I think, for count variable we should upcast to Int64 if it is of type Int8, Int16, or Int32, preventing the error.
