Use roaring bitmap in hash join for tracking hash collisions

**Is your feature request related to a problem or challenge? Please describe what you are trying to do.**

to improve memory efficiency at a cost of compression, but possibly can allow a wider range of join schemes to be executed without backing to sort merge join

The issue names no files, tests, or entry points. Start by locating DataFusion's hash join implementation and its collision-tracking logic, then determine how a roaring bitmap would affect memory use and join execution; done requires an agreed design and validation that the relevant join schemes still work.
