### Is your feature request related to a problem or challenge? If we move the built-in function out of the optimizer, it is more easy to extend/adapt the optimizer rule to other UDAFs. For example, change the `first_value` (datafusion builtin) to `first_value` (UDAF) in `replace_distinct_aggregate`. Discussion from https://github.com/apache/datafusion/pull/10648#discussion_r1617221359 ### Describe the solution you'd like 1. Move the `replace_distinct_aggregate` to functions-aggregate as part of the *builtin* optimize rule, and register the rule to optimizer rules 2. Enable FunctionRegistry in the optimizer rule, we always get the function with the name `"first_value"` here, if they have `first_value` UDAF, they can take advantage of this rule by replacing the `first_value` to their version. ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
