### Is your feature request related to a problem or challenge? For a query like: ```sql SELECT +'a' ``` The only message that the end user of an application built atop of DataFusion sees is: ``` Error during planning: Unary operator '+' only supports numeric, interval and timestamp types ``` We want to provide a richer message that _references and highlights locations in the original SQL query_, and contextualises and helps the user understand the error. In the end, it would be possible to display errors in a fashion akin to what was enabled by #13664 for some errors:  See #14429 for more information. ### Describe the solution you'd like Attach a well crafted `Diagnostic` to the `DataFusionError`, building on top of the foundations laid in #13664. See #14429 for more information. ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
