> [C++] list_parent_indices output type should not depend on input type

> Currently, the {{list_parent_indices}} output type is the input list offset
> type. But that doesn't really make sense: the parent indices are simply
> indices in the list array, they are not bounded by the offset size (even a
> list array with 32-bit offsets can have a length larger than 2**32, for
> example if it's mostly nulls).
