The change introduces the following:
- BiometricPrompt communicatates with BiometricPromptService (new)
system service. The service does the decision making for which
biometric modality to use.
- As a result, a lot of logic is moved from <Biometric>Manager
to BiometricPrompt. FingerprintManager now does not care about
BiometricPrompt logic anymore (reverts several P changes).
Face, and all future <Biometric>Service interfaces must be protected by
the signature-only MANAGE_BIOMETRIC permission. Settings, SystemUI, and
BiometricPromptService are their only clients.
