Add pad animation for STAGE_CENTER & STAGE_GUIDED

1. STAGE_CENTER reference
   - String : security_settings_sfps_enroll_finger_center_title
   - raw : udfps_center_hint_lottie

2. STAGE_GUIDED
   - String : security_settings_fingerprint_enroll_repeat_message
   - raw : udfps_center_hint_lottie (Same with STAGE_CENTER)

Bug: 228100413

Test: manually verified on Settings > Security > Face & Fingerprint
Unlock > Fingerprint Unlock > Touch & Hold fingerprint sensor page

Test: make RunSettingsRoboTests ROBOTEST_FILTER=
"com.android.settings.biometrics.fingerprint
.FingerprintEnrollEnrollingTest"
