Tracking: distinct aggregation

[likg227]

• add expand operator feat: expand operator #3563
• support selective aggregate RFC: selective aggregates #3506. We don't need provide this feature to user but use it interneally now.
  • (optional)parse and bind FILTER(WHERE..)
  • add Condition for PlanAggCall
  • implement filter for batch agg.
  • implement filter for streaming agg.
    • pk of expand is wrong. #4179
• add DistinctAgg rule for optimizer. IMO, there is no much difference between implementing it in planner and implemnting it as a rule, but a rule may provide more flexbility. feat(optimizer): distinct agg. #3717
