Review Comment:
After exploring all options, I get the impression that this option that
@alamb mentioned before:
> Update `BoundedWindowAggExec` to produce the field names declared by the
`WindowAggExec`
is the most consistent path forward. It tends to produce overly verbose
column names, but all the other options seems to suffer from some kind of a
problem. AFAICT this approach is similar to what @berkaysynnada mentioned as
[his first solution alternative in the issue
description](https://github.com/apache/arrow-datafusion/issues/6492) as well.
@alamb, @comphead: What do you think? Should we move forward with this
approach?
