Update screen lock and biometrics options in order

Previously the screen lock and biometrics order is :
UI & UX: b/182806496, b/183649070
- PIN • Face • Fingerprint
- Pattern • Face • Fingerprint
- Password • Face • Fingerprint

By requirement, we need to reverse Fingerprint & Face position
- PIN • Fingerprint • Face
- Pattern • Fingerprint • Face
- Password • Fingerprint • Face

Also remove unused strings
