I see that planning the ExchangeSinkExec takes a few milliseconds when benchmarking simple queries with 10K fields. It spends time checking if we need to realign the incoming pages. However, the exchange has the exact same attributes as its child, so the incoming layout should match its attributes perfectly. This change removes the realignment.
I will open a follow-up PR to remove this flag. I will also look into removing the alignment of OutputExec.
