Summary:
Fixes T10423. Ref T11524. This changes `diffusion.rawdiffquery` to return a file PHID instead of a blob of data.
This is better in general, but particularly better for huge diffs (as in T10423) and diffs with non-utf8 data (as in T10423).
Test Plan:
- Used `bin/differential extract` to extract a latin1 diff, got a clean diff.
- Used `bin/repository reparse --herald` to rerun herald on a latin1 diff, got a clean result.
- Pushed latin1 diffs to test commit hooks.
- Triggered the the too large / too slow logic.
- Viewed latin1 diffs in Diffusion.
- Used "blame past this change" in Diffusion to hit the `before` logic.
