Review Comment:
IIUC, when we replace SubqueryAdaptiveBroadcastExec to
SubqueryBroadcastExec, we would add a broadcast exchange on the top of child
then AQE would reuse the broadcast exchange. Then can
`SubqueryAdaptiveBroadcastExec.child` be same with
`SubqueryBroadcastExec.child`(broadcast exchange) ?
