Decouples the remainder of challenges from LockSettingsService. Clients that require Gatekeeper HATs that wrap challenges should request the Gatekeeper Password, then request LockSettingsService to verify(GatekeeperPassword, Challenge). If the challenge is biometric-related, it must be generated after LockSettingsService completes verifyCredential, since LockSettingsService internally does generateChallenge/resetLockout/revokeChallenge.
