Fix FingerprintEnrollmentActivity rotaiton crash

1. When FragmentActivity rotated, FragmentManager will call default
   fragment constructor w/o parameters. Remove parameters of
   FingerprintEnrollIntroFragment constructor. And also remove
   BiometricsFragmentFactory because of useless now.
2. Remove some LiveData inside AutoCredentialViewModel because it causes
   jitter on activity transition.
3. Save and restore data inside AutoCredentialViewModel for handling
   activity recreation during rotation.
4. clear FingerprintEnrollIntroViewModel.mActionLiveData to prevent
   that activity gets previous action after recreate
5. Fix launching wrong activity during setupwizard
