Cole Miller 00b9127309 git: More rigorously test excerpt syncing for split diff, and fix a couple of bugs (#49907) ...

This PR adds a more rigorous test for the excerpt syncing logic in
`SplittableEditor`, in preparation for refactoring that code, since
we've had some bugs there.

The new test covers
- edits within the RHS multibuffer
- edits to the individual main buffers, not necessarily within the
excerpt bounds of the split diff
- excerpt expansion
- excerpt removal
- excerpt recalculation based on diff hunk ranges

Bugs fixed:
- incorrect edit merging logic in `patches_for_range`
- `merge_excerpts` leaving stale excerpt IDs in `excerpts_by_path`

Before you mark this PR as ready for review, make sure that you have:
- [x] Added a solid test coverage and/or screenshots from doing manual
testing
- [x] Done a self-review taking into account security and performance
aspects
- [ ] Aligned any UI changes with the [UI
