Follow-up to SPARK-36082. The original change added an abstract def mode: BroadcastMode to the BroadcastExchangeLike trait so that LogicalQueryStageStrategy could distinguish null-aware from regular hashed broadcast stages. Adding an abstract method to a public trait is source- and binary-incompatible for downstream implementations. Inspect outputPartitioning instead. Every BroadcastExchangeLike must already produce BroadcastPartitioning(mode) to satisfy the BroadcastDistribution(mode) requirement on join sides, so the mode is already exposed through the existing SparkPlan contract and the new abstract method is unnecessary.

Adding an abstract method to a public trait is source- and binary-incompatible for downstream implementations.
Inspect outputPartitioning instead. Every BroadcastExchangeLike must already produce BroadcastPartitioning(mode) to satisfy the BroadcastDistribution(mode) requirement on join sides, so the mode is already exposed through the existing SparkPlan contract and the new abstract method is unnecessary.
Why are the changes needed?
Avoid binary-incompatible mode method on BroadcastExchangeLike.
