Preemptively hide UDPFS icon on biometric authenticated

To avoid overlap with the unlock icon after face auth
is successful on AOD.

We intentionally check for isBiometricAuthenticated instead
of isUnlocked because checking keyguardStateController#isUnlocked
would cause a delay in showing UDFPS on the transition from HOME => AOD,
(since the isUnlocked state doesn't immediately get updated)
which would be unintended.
