[CORE] Optimize the verboseString of ColumnarShuffleExchangeExec

[Zouxxyy]

What changes are proposed in this pull request?

before:
ColumnarExchange SinglePartition, ENSURE_REQUIREMENTS, [plan_id=744], [shuffle_writer_type=hash], [OUTPUT] List(sum:DoubleType, count:LongType), [OUTPUT] List(sum:DoubleType, count:LongType)


after:
ColumnarExchange SinglePartition, ENSURE_REQUIREMENTS, [plan_id=710], [shuffle_writer_type=hash], [output=[sum#133: double, count#134: bigint]]

The reason why the OUTPUT appeared twice previously is that verboseString internally calls simpleString. Moreover, simpleString generally does not include output information, so this PR simply removes it.

Can we preserve the data type?
