Cheng Hao cc552e0428 [SQL] [Minor] Update the SpecificMutableRow.copy ... When profiling the Join / Aggregate queries via VisualVM, I noticed lots of `SpecificMutableRow` objects created, as well as the `MutableValue`, since the `SpecificMutableRow` are mostly used in data source implementation, but the `copy` method could be called multiple times in upper modules (e.g. in Join / aggregation etc.), duplicated instances created should be avoid.
