### Is your feature request related to a problem or challenge? First / Last aggregate function has the method `fn reverse_expr(&self) -> Option<Arc<dyn AggregateExpr>>` that returns another new `AggregateExpr`. We can't support this method since `AggregateExpr` is in `functions-aggregate` (I plan to move it here in #9960). I propose that we move `AggregateUDFImpl` to `functions-aggregate`. The overall idea is that we move aggregation functions struct or trait including logical and physical to `functions-aggregate`. keep other *common* struct or trait in `datafusion-expr` and `datafusion-physical-expr-common` respectively. ### Describe the solution you'd like _No response_ ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
