Reimplement Commit comments in the MR context (showing & replying)
This stems from the Merge Request refactor effort (gitlab-ce#48034)
Upon launch, some features had been disabled/lost and need to be recovered.
The comments left on commits are no longer being displayed in the MR context.
Tasks
- display commit comments in the MR changes tab when present
- allow these to be replied to
