Spark already supports [runtime filter injection](https://github.com/apache/spark/blob/master/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/optimizer/InjectRuntimeFilter.scala). We should pay attention to whether this causes comet operators to fall back, and how to make the filters generated by Spark take effect in the comet native plan. Additionally, for bloom filter, we may need to implement a new function to be compatible with scenarios where execution falls back to vanilla spark.
