### Description Currently for `PythonEvalExec`, Gluten will try to offload if backend has same implementation as udf in its built-in functions and fallback if native validation failed. For Velox backend, since the data between each op is `VeloxColumnarBatch` and can export to `ArrowArray` through velox's bridge, ideally w/o memory copy. To do this, we need to do a `ensureLoad` and `ensureOffload` which are responsible for arrow array import and export. Besides, we also need to add a preproject to assure there is no additional projections happened in this op. -- This is an automated message from the Apache Git Service.
