[FEA] Support min and max for arrays

[revans2]

Is your feature request related to a problem? Please describe.
Some changes went in recently where min and max hash aggregates were added for structs with arrays in them, but not arrays by themselves.

#8638

This covers most of #3153 but does not cover everything we need for a customer. In the short term I can work around it by hacking things up and wrapping the array with a struct. But that is not a good long term solution to the problem.

Describe the solution you'd like
I would like CUDF and us to support group by aggregations for min and max on arrays at the top level.

Depends on rapidsai/cudf#13676.

BTW, this should be the generalized version of #4929.
