Add support for Window expressions

[andygrove]

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 #2721 (comment) on currently supported functions

• rank
• dense_rank
• row_number
• lag
• lead
• ntile
• cume_dist
• nth_value
• ignore nulls
• respect nulls
