4/n: Add face authentication framework

This change is cherry-picked and rebased from AOSP
https://android-review.googlesource.com/c/platform/frameworks/base/+/660242

Add face recognition as an identification method, following fingerprint
design. Unlike fingerprint, only one face template can be enrolled per
user, and a vendor message is passed from the HAL all the way to the
client callback to allow GUI indication about the enrolled face
templates.

Add FaceAuthenticationManager and FaceService.
Add face authentication capability to TrustManager and Keyguard.
Modify TrustManager and KeyguardUpdateMonitorCallback fingerprint code
to support generic biometric method to eliminate duplications.
Add BiometricSourceType enum to keep track of the specific biometric
method.

Test: biometric authentication still works on the device
