Review Comment:
Because Spark's default `outputPartitioning` is `UnknownPartitioning`, if we
add `child.outputPartitioning` to `CometUnaryExec` as default, it will possibly
change `outputPartitioning` if we don't notice it.
Currently `CometExec` uses original Spark plan's `outputPartitioning` as
default which is safer option, I think. Except for the case that Spark
dynamically changes output partitioning during execution like AQE, it should be
correct because Comet doesn't change output partitioning from Spark.
