Keep this on the CPU, but possibly convert its children under it to run on the GPU if enabled.
Keep this on the CPU, but possibly convert its children under it to run on the GPU if enabled. By default this just returns what is wrapped by this. For some types of operators/stages, like SparkPlan, each part of the query can be converted independent of other parts. As such in a subclass this should be overridden to do the correct thing.
