Pass Timeout back to upper biometric preference

Browse Source 
When FaceSettings or FingerprintSettings are closed because of onStop(),
this information can't been passed back to previous Preference screen,
CombinedBiometricSettings, because handlePreferenceTreeClick() from
AbstractPreferenceController class only can launchActivity() throguh
preference's Context.

In order to recevice the activity result code from FaceSettings or
FingerprintSettings, add handleBiometricPreferenceTreeClick() method in
BiometricStatusPreferenceController. Then CombinedBiometricSettings uses
this method to show FaceSettings or FingerprintSettings through
launchActivityForResult().

Bug: 263057093
Test: atest BiometricNavigationUtilsTest
Test: Manually open camera through double-click power key on different
      pages inside "Face & Fingerprint Unlock"
