REFACTOR: Simplify converter steps in migration tooling (#29779)
* Remove unused `report_progress_in_percent` option from step
* Remove `use_custom_progress_increment` option from the step because we can figure it out by looking at the progress
* Introduce `StepTracker` to for logging warnings and errors and tracking step progress
* Make it easier to log warnings and errors in all methods of `Step` without the need to pass around a `stats` object
