### Is your feature request related to a problem or challenge? While moving `count` to UDAF, I found that we need to call UDAF in the optimize rule [`single_distinct_to_groupby`](https://github.com/apache/arrow-datafusion/blob/main/datafusion/optimizer/src/single_distinct_to_groupby.rs). Similar to `ArrayFunctionRewriter`, we need to move the rule `single_distinct_to_groupby` out of the core. ### Describe the solution you'd like 1. Move common optimizer things to `optimizer-common` crate or `datafusion-expr` crate 2. Move `single_distinct_to_groupby` to `function-aggregate`. ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
