[DISCUSS] [DataFusion] Unify Function Interface (remove BuiltInScalarFunction)

I would like to bring wider visibility to a proposal[1] to unify the
function interface in DataFusion.

The TLDR is to remove BuiltInScalarFunction and ensure all functions can
implemented as `ScalarUDF`

There is a small API change to ScalarUDF proposed as well[2].

If you are interested, please leave comments on the ticket and/or PR.

Thank you,
Andrew
