Remove direct calls to LowLevelCommitQuery

Summary: Ref T2783. This cleans up some more of the direct VCS access calls. If the repository is local, this boils down to an in-process call. If not, it uses Conduit to make an intracluster request.

Test Plan: Used `reparse.php --message <commit> --trace` to observe cluster request.
