Make FingerprintManager show BiometricPrompt for UDFPS

For apps that are still using FingerprintManager, have the system show
BiometricPrompt when authenticating with a UDFPS sensor. This will
ensure that the user is directed to authenticate on the correct part of
the screen, rather than requiring the app to draw an authentication UI.

Test: FingerprintManager test app, Keyguard, and Settings.
