The aggregation std with batch processing has been implemented for groupby and windowing contexts. For reduction context, currently we only support standalone processing for a single input column.

We need to support batch processing for std, as requested by spark-rapids (NVIDIA/spark-rapids#62 and NVIDIA/spark-rapids#7891).

Close this, as it is no longer needed for spark-rapids.
