Simon Charette df236b0bcb [5.1.x] Fixed #35665 -- Fixed a crash when passing an empty order_by to Window. ...

This also caused un-ordered sliced prefetches to crash as they rely on Window.

Regression in e16d0c176e that made OrderByList
piggy-back ExpressionList without porting the empty handling that the latter
provided.

Supporting explicit empty ordering on Window functions and slicing is arguably
a foot-gun design due to how backends will return undeterministic results but
this is a problem that requires a larger discussion.

Refs #35064.

Thanks Andrew Backer for the report and Mariusz for the review.
