**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** `Accumulator` is the state of an aggregate function, and has nothing to do with a logical expression. The current blocker is AggregateUDF which mixes both the function signature and the function implementation. AggregateUDF exists in `datafusion-expr` because of its signature parts. **Describe the solution you'd like** 1. Move Accumulator into `datafusion-physical-expr`. 2. Split AggregateUDF into parts, one remains in `datafusion-expr` that represents AggregateUDF's signature, and the other in `datafusion-physical-expr` for its implementation. **Describe alternatives you've considered** Don't move. -- This is an automated message from the Apache Git Service.
