[Refactor] [DataSet] Refactor key selector translation in DataSet API.
This PR refactors the translation of `SelectorFunctionKey`s in the DataSet
API.
It removes a lot of duplicate code to create key extracting mappers and key
removal mappers and reformats overlong lines.
It also cleans up most compiler warnings in the touched classes.
