`Tracking`: Code Fixes

> **Note**
> This is a "meta" issue for tracking purposes since GitHub does not support special types of issues.

Code fixes are code actions that react on diagnostics and can fix them. In VS, they are represented with a lightbulb and a small cross on it.

We should make code fixes easy to create, test, and extend.
