val aggregationMode: (Option[AggregateMode], Option[AggregateMode])

The distinct modes of AggregateExpressions.
The distinct modes of AggregateExpressions. Right now, we can handle the following mode:
- Partial-only: all AggregateExpressions have the mode of Partial;
- PartialMerge-only: all AggregateExpressions have the mode of PartialMerge);
- Final-only: all AggregateExpressions have the mode of Final;
- Final-Complete: some AggregateExpressions have the mode of Final and others have the mode of Complete;
- Complete-only: nonCompleteAggregateExpressions is empty and we have AggregateExpressions with mode Complete in completeAggregateExpressions; and
- Grouping-only: there is no AggregateExpression.
