Hey guys I am working on this PR <https://github.com/arrow-kt/arrow/pull/1481>

And I detected the Problem why I always get this error:
```
e: error: Arrow's annotations can only be used on Kotlin classes. Not valid for error.NonExistentClass
```
In the Debug stacktrace it occurs that the failure happens in `arrow-core-extensions` more specifically, the kapt Task `kaptKotlin`
I have 2 assumptions:
- Either there is a problem with codegen and I need to make this PR bigger than expected. Moving everything out of arrow-extras-data.
 - Or I am missing an import in gradle

I already moved more data-types to arrow-core-data, but it always fails with NonEmptyListBimonad
