Add support for bloom_filter_agg

[andygrove]

What is the problem the feature request solves?

Some TPC-H queries use bloom_filter_agg, and Comet does not have a native implementation yet.

A workaround is to set spark.sql.optimizer.runtime.bloomFilter.enabled=false.

We need to implement an equivalent of Spark's org.apache.spark.sql.catalyst.expressions.aggregate.BloomFilterAggregate.

Accumulating some notes for this. Here's the Spark design doc on the feature:

It looks like we already have the filter support thanks to #179.

BloomFilterAggregate is only supported by ObjectHashAggregate or SortAggregate. But in Comet, we only support HashAggregate so far.
