Use android debugImplementation and releaseImplementation

Is there a way to specify `debugImplementation` and `releaseImplementation` for android dependencies?

For example, you can log useful debugging info inside myplugin-debug.aar. When building for release, proguard can strip these logs away.

```gradle
// desired output to mainTemplate.gradle
debugImplementation files('./libs/myplugin-debug.aar')
releaseImplementation files('./libs/myplugin-release.aar')
```

At the moment I am constantly adding/removing `Log.d` calls used for debugging.
