What is the problem the feature request solves?
Currently we support BroadcastExchange if it is under BroadcastHashJoin in Comet.
Besides broadcast join, BroadcastExchange can also occur under SubqueryBroadcastExec for dynamic pruning expression. Because Spark BroadcastExchange assumes it is row-based so we cannot simply transform BroadcastExchange under SubqueryBroadcastExec into Comet's broadcast operator.
We need to come out with a Comet SubqueryBroadcastExec which supports Comet's BroadcastExchange.
