Thank you @jayzhan211 -- this looks great to me
I also updated this PR's description to add some additional rationale

Which issue does this PR close?
Part of #10731
Inspired from #10807 (comment)
Close #10807
Rationale for this change
The reason to add a stub is that as we pull the aggregate functions out of the core and into
datafusion-functions-aggregatethe existing optimizer passes don't depend on datafusion-functions-aggregate.Thus by using stubs we'll keep the optimizer passes decoupled from the built in aggregate functions as much as possible.
