**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** Built-in Window Functions and Aggregate functions are handled quite differently. This decreases both readability and code reuse. As an example, `BuiltInWindowFunctionExpr` uses record batch during [creation](https://github.com/apache/arrow-datafusion/blob/522a2a4adea48777f330cac074db94a4da3ea66b/datafusion/physical-expr/src/window/built_in_window_function_expr.rs#L49). However, `AggregateExpr` doesn’t require it (as can be seen in the [link](https://github.com/apache/arrow-datafusion/blob/522a2a4adea48777f330cac074db94a4da3ea66b/datafusion/physical-expr/src/aggregate/mod.rs#L69)). **Describe the solution you'd like** I want to refactor code such that their handling is similar. **Describe alternatives you've considered** N.A **Additional context** N.A -- This is an automated message from the Apache Git Service.
