Remove dead "Service Lock" code from Almanac

Summary:
Depends on D19315. Ref T13120. Ref T12414. See PHI145. See PHI473. I want to move Almanac services to ModularTransactions but ran into this old piece of dead/unused code along the way.

Long ago, Almanac services could be individually "locked", but this didn't really work out very well. It was replaced by "Can Manage Cluster Services" in D15339 and prior changes, but not all of the old "Lock" code got cleaned up.

I don't expect to restore this feature, so clean it up now.

Test Plan:
  - Grepped for `AlmanacServiceTransaction::TYPE_LOCK`, `TYPE_LOCK`, etc.
  - Grepped for `updateServiceLock()`, no callsites.
