### Is your feature request related to a problem or challenge? As part of https://github.com/apache/arrow-datafusion/issues/8045 we need to ensure that scalar UDFs have the same functionality as built in functions. One gap that currently exists is "aliases". For example, `pow` and `power` are both resolved to the same function. ### Describe the solution you'd like Implement aliasing for ScalarUDF Basically : 1. Add aliasing to ScalarUDF API 2. Hook it up so that ScalarUDF can accept aliases and that the planner can use them 3. Write an end to end test (probably in https://github.com/apache/arrow-datafusion/blob/32fe1761287c9b58294a54805a0fcafc4ab046b8/datafusion/core/tests/user_defined/user_defined_scalar_functions.rs#L1-L0) I am envisioning creating a scalar UDF with a new function `with_alias`. Something like ```rust ScalarUDF::new( "pow", &Signature::exact(input_types, volatility), &return_type, &fun, ) .with_alias("power") ``` Currently the alias list is here: https://github.com/apache/arrow-datafusion/blob/094a0e2d0c8c1f71c985c7bfdf21433ebc8f203e/datafusion/expr/src/built_in_function.rs#L1374 ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
