FingerprintStats Westworld Migration

Adds 4 fingerprint atoms: NumFingerprints,
FingerprintAcquired, FingerprintAuthenticated, and
FingerprintErrorOccurred. Right now, these should have a 1-1 mapping
with dumpsys fingerprint. More acquire and error codes can be added
pending Metrics Council approval.

Note: I do not know how to test crypto fingerprints,
Note: Most of the logging likely fits better in BiometricService, but
given that it shares code with FaceService and we do not have approval
to log FaceService, I had to put the logic in FingerprintService.
