Upgrade window UDF api

[Michael-J-Ward]

Is your feature request related to a problem or challenge? Please describe what you are trying to do.

datafusion is in process of removing their built-in window-functions, which our current window function relies on. sum has already been removed which brakes the q11_important_stock_identification.py tpch example.

Additional context

AggregateFunction::Sum enum variant is still defined, but can not be used.

I suspect that the proper solution is to register the new UDAFs with the function registry.

As a workaround for releasing 39, I explicitly match on name == "sum" and redirect to the UDAF.

@timsaucer could you take a look at this once #728 is merged?

@Michael-J-Ward I know this issue was already closed but I have proposed a method to remove the work around.
