> In https://github.com/apache/spark/pull/7752 we added `FromUnsafe` to convert
> nexted unsafe data like array/map/struct to safe versions. It's a quick
> solution and we already have `GenerateSafe` to do the conversion which is
> codegened. So we should remove `FromUnsafe` and implement its codegen version
> in `GenerateSafe`.
