Use biometricUnlockController state change to show the unlock ripple.

Bug: 270989070
Test: atest AuthRippleControllerTest
Test: manually
  1. Enroll side fps with touch to unlock anytime enabled
  2. Press the power button to lock the device
  3. Touch the power button quickly after that
  4. Device should unlock and show launcher with unlock animation ripple
  5. Repeat this 10 times as the time taken between onStartedGoingToSleep & onFinishedGoingToSleep is not always the same.
  6. Also verify that the auth ripple is visible while using SFPS from AlternateBouncer (by tapping a notification on lockscreen) and by using SFPS from bouncer.
