public percentage methods for fill and trim task

Provides public methods to get the percentage for the fill and trim
task. These can be used by 3rd party plugins to get the calculated
percentage or get the values of the processed/total amount of chunks.

Possible usages I have in mind:
- Boss bar showing a progress of the fill task
- Action bar showing the status
- ...
