Is your feature request related to a problem or challenge?

The changes in #11564 introduced AccumulatorArgs::is_reversed. This indicates that the sort order of the aggregation is reversed.

The existing implementation of NthValueAgg tracks this as internal state. Instead of that use AccumulatorArgs::is_reversed.

Describe the solution you'd like

Refactor NthValueAgg to use AccumulatorArgs::is_reversed.
