Add a Herald pre-commit field for detecting LFS usage

Browse source 
Summary: Depends on D18825. Ref T7789. See PHI131. Allows installs to selectively disable LFS by adding Herald rules to block commits that use LFS.

Test Plan:
  - Wrote an LFS rule ("When commit uses git lfs, block commit").
  - Pushed an LFS commit: rejected.
  - Pushed a non-lFS commit: success.
