Add support for Window expressions
What is the problem the feature request solves?
Dedicated window functions such as rank, dense_rank, row_number, lag, lead, ntile, cume_dist, percent_rank, and nth_value are not currently supported and will fall back to Spark.
See https://github.com/apache/datafusion-comet/issues/2721#issue-3597823392 on currently supported functions
- [ ] rank
- [ ] dense_rank
- [ ] row_number
- [ ] lag
- [ ] lead
- [ ] ntile
- [ ] cume_dist
- [ ] nth_value
- [ ] ignore nulls
- [ ] respect nulls
