Add hash distribution and sort grouping only when dynamic partition insert

    Description

      Now in BatchExecSinkRule, we don't have static partitions, if it is a partitioned table, will add hash distribution and sort grouping. It is wrong:

      1. Group only when dynamic partition insert (not all partition fields are static partitions)
      2. We can just hash and sort dynamic partition fields instead of all partition fields.
