[I] degenerate 0 sized fixed size list misbehaves under take [arrow-rs]

Jefffrey opened a new issue, #10914:
URL: https://github.com/apache/arrow-rs/issues/10914

   ### Describe the bug
   
   got codex to run some correctness checks against take kernel, it surfaced this bug:
   
   ```rust
   // arrow-select/src/take.rs
   
   #[test]
   fn test_take_zero_sized_fixed_size_list() {
       let input = FixedSizeListArray::try_new_with_length(
           Field::new_list_field(DataType::Int32, true).into(),
           0,
           Arc::new(Int32Array::new_null(0)),
           None,
           3,
       )
       .unwrap();
   
       let indices = UInt32Array::from(vec![2, 0]);
       let result = take(&input, &indices, None).unwrap();
   
       assert_eq!(result.len(), 2);
   }
   ```
   
   on main this test fails:
   
   ```sh
   ---- take::tests::test_take_zero_sized_fixed_size_list stdout ----
   
   thread 'take::tests::test_take_zero_sized_fixed_size_list' (35753445) panicked at arrow-select/src/take.rs:3232:9:
   assertion `left == right` failed
     left: 0
    right: 2
   ```
   
   it should succeed
