Polars is significantly faster than the current pyarrow-based sort. This PR uses polars for the internal sort implementation if available. No API changes needed.
On my laptop, this makes sorting 1GB about 2x faster:

Release Tests
While the exact release process relies on Anyscale internal tooling, the tests we run during the releases are located at https://github.com/ray-project/ray/blob/master/release/.buildkite/build_pipeline.py
