12/n: Remove the need for setActiveUser(int)

This is already semi-combined in the Fingerprint/FaceService layer,
for example authenticate() already updates the active group. This
change makes the remainder of user-specific operations (resetLockout,
enroll, etc) atomic from a caller's perspective.

Also fixed some fingerprint naming (passing userId through groupId
parameter since groupId is not used). GroupId is going to be removed
in a follow-up CL.

Removed unused rename() from IFaceService.aidl / FaceService.java

Bug: 157790417
Test: For fingerprint/face, do each of the following
Test: Enroll, rename, auth, remove each for multiple users
Test: 1) Set up work profile with shared challenge
      2) Lock out owner and work profile
      3) Unlock keyguard via password
      4) BiometricPromptDemo for work profile and owner have
         lockout reset
