Review comment:
Looks `DynamicPartitionPruningSubquery` and
`DynamicShufflePruningSubquery` are almost the same, so we need this new
predicate? Could we add a value to represent a pruning type in a class field of
`DynamicPruningSubquery` like this?
```
case class DynamicPruningSubquery(
pruningKey: Expression,
buildQuery: LogicalPlan,
buildKeys: Seq[Expression],
broadcastKeyIndex: Int,
onlyInBroadcast: Boolean,
exprId: ExprId,
pruningType: PruningType) <---- This?
```
