Do not display adaptive auth string on dismissible keyguard

After the device is locked out by adaptive auth, if it's unlocked again
by the user using face auth and doesn't skip to the home screen (i.e.
the keyguard is dismissible with swipe), do not display the adaptive
auth string in the keyguard bottom area.

Flag: EXEMPT bugfix
Fix: 353196564
Test: atest KeyguardIndicationControllerTest
Test: 1. Set up face auth and select not to skip lock screen
      2. Trigger 5 primary auth and biometric auth failures from
         BiometricPrompt, which will lock the device out
      3. Unlock the device again with face auth and do not swipe to skip
         lock screen
      4. Check that the adaptive auth string doesn't appear in the
         Keyguard bottom area
