Summary:
Ref T13137. See that task for discussion.
When we show a diff-of-diffs, we often render stubs for files which didn't change between the diffs. These stubs usually aren't a big deal, but for certain types of changes (like refactors) they can create a lot of clutter.
Instead, hide these stubs and show a notice that we hid them.
Test Plan:
- Created a revision affecting 4 files.
- Updated it with a diff that changed only 1 of the 4 files.
- Added an inline comment to a different file.
- Viewed the diff of diffs.
- Before: 4 changesets with two "nothing changed" stubs.
- After: 2 changesets with the stubs hidden.

Summary:
Ref T13137. The "analyze/cache data about changesets" step is becoming more involved. We recently added detection for generated code to support "Ignore generated changes" in Owners, and I now plan to hash the new file content so we can hide changes which have no effect.
Before adding this new hashing step, pull the "detect copied code" and "detect generated code" stuff out and move them to a separate `ChangesetEngine`. Then support doing a changeset rebuild directly with `bin/differential rebuild-changesets`.
This simplifies things a bit and makes testing easier since you don't need to keep creating new revisions to re-run copy/generated/hash logic.
Test Plan: Ran `bin/differential rebuild-changesets --revision Dxxx`, saw changesets rebuild. See also next change.
