### Is your feature request related to a problem or challenge? In #17986 one of the updates we made was to change the SQL utility `convert_data_type(&self, sql_type: &SQLDataType) -> Result<DataType>` to return a `FieldRef`; however, extension `TypePlanner`s can't take advantage of this to plan `SQLDataType`s to Arrow extension types (and there are a number of built-in `SQLDataType`s that have existing extension types, such as UUID). If we update the type planner to incorporate these types we can start to open up the utility of the SQL parser for systems that need wider type support (e.g., my favourite one...geometry!). ### Describe the solution you'd like We can add a member to `TypePlanner` that returns a field (falling back on the existing member for backward compatibility). ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
