While working on #9599 @scovich and I noticed that `variant_get(...,
List<Int64>)` returns a shredded List<Struct{value, typed_value:Int64}> instead
of `List<Int64>`
https://github.com/apache/arrow-rs/pull/9599#discussion_r2984436071
> I believe the newly added
test_variant_get_list_like_unsafe_cast_preserves_null_elements unit test
confirms the wrong behavior:
Caller passes DataType::List(Arc::new(Field::new("item", DataType::Int64,
true))) (= List<Int64>)
But the test expects List<Struct{value, typed_value:Int64}> (= shredded
variant array)
**Describe the solution you'd like**
Make `VariantToListArrowRowBuilder` build arrays depending on the requested
output type, not just shredded struct.
