Move Differential to EditEngine comments

Summary:
Ref T11114. This is a transitional change that breaks a bunch of stuff. I'll hold it until I've restored features.

This stuff works:

  - Commenting.
  - Subscribers/tags/reviewers.
  - Pinning.
  - Drafts.

This stuff does not work yet:

  - Preview of inline comments.
  - Probably submitting inlines, whatsoever.
  - Comment-area warnings like "There are failing tests."
  - All meaningful actions (accept, reject, etc).

Test Plan: Commented on a revision. Essentially nothing else works yet.
