> In FLINK-25238, we fix the ArrayDataSerializer to support copying customized type of array data with similar way in MapDataSerializer.
> The MapDataSerializer#toBinaryMap always contains copy semantics implicitly
> but ArrayDataSerializer#toBinaryArray not.
> So the returned value of ArrayDataSerializer#toBinaryArray will be covered by new copied data.
> We should always copy from the returned value of ArrayDataSerializer#toBinaryArray in ArrayDataSerializer#copy explicitly.
