32/n: Move Face1.0 into its own wrapper

This change removes BiometricServiceBase. At this point, the framework
is able to support multiple HIDLs for each sensor type.

Also re-adds some things that were forgotten, e.g.
1) Enrollment limit
2) Update authenticatorId after enroll

Bug: 157790417
Test: enroll, authenticate using face
