Remove Controller->renderHandlesForPHIDs()

Summary: Ref T7689. Remove all remaining callsites for this method.

Test Plan:
- Viewed a custom policy; viewed handles in the policy rules.
- Viewed a Releeph product; viewed "Pushers".
- Viewed a project; viewed "Watchers"; viewed "Members"; viewed "Looks Like".
- Viewed repository edit; viewed "Credential"; viewed "Storage Service"; viewed "Projects".
- Viewed repository detail; viewed "Projects".
- Viewed commit; viewed (faked) "Reverts"; viewed (faked) "Reverted By".
  - These are kind of a pain to generate so I faked 'em.
