Liang-Chi Hsieh 6f18ac9e99 [SPARK-27241][SQL] Support map_keys and map_values in SelectedField ... ## What changes were proposed in this pull request? `SelectedField` doesn't support map_keys and map_values for now. When map key or value is complex struct, we should be able to prune unnecessary fields from keys/values. This proposes to add map_keys and map_values support to `SelectedField`. ## How was this patch tested? Added tests. Closes #24179 from viirya/SPARK-27241.
