Start UDFPS sensors only after BiometricPrompt UI is showing
Since UDFPS sensors have a UI affordance, and the affordance is
controlled by FingerprintAuthenticationClient, start the prepared
sensor only after the BiometricPrompt dialog is done animating.
Plumbing-wise, adds:
1) Adds AuthSession.STATE_AUTH_STARTED_UI_SHOWING
2) Adds IBiometricSysuiReceiver#onDialogAnimatedIn
Since not all sensors are started immediately anymore, adds
logic in BiometricScheduler when attempting to cancel auth
for a sensor that's waiting for cookie (HAL still idle).
