Reland:Launch multiple biometric enrollment when no biometric is enrolled

When a user clicks the biometric item in the Device unlock page and no
biometric is enrolled:
- Fingerint clicked: Launch fingerprint enroll then face enroll.
- Face clicked: Launch face enroll then fingerprint enroll.

Also fixed work profile not working issue:
- Use BiometricEnrollActivity.InternalActivity to provide correct userId
  for work profile.
- Use the canAuthenticate() function that take userId as input.
