Feature proposal: Applying suggested changes should create "fixup" commit
### Problem to solve
Applying suggested changes creates a new commit, but it would be cleaner and nicer if it was a fixup commit so that it can be squashed into the original commit and avoid clutter in the commit history.
### Target audience
The merge request author (or other person fixing comments) will have an easier life applying fixes.
### Proposal
When applying a suggested change on MR the commit that gets created should be a fixup commit so that it can be squashed correctly wiht `git rebase -i -- autosquash`.
### What does success look like, and how can we measure that?
Same as proposal.
