1/n: Add ClientMonitors for authenticatorId invalidation

Browse Source 
InvalidationRequesterClient (for requesting other clients to
invalidate) will be fully implemented in subsequent CL's.

InvalidationClient (for requesting HALs to invalidate authenticatorId)
should be complete at this point.

Also updates BiometricUtils to persist a "invalidationInProgress"
flag on-disk for each <sensorId, userId> pair.

Bug: 159667191
Test: No effect on existing devices
Test: Existing enrollments not affected

Change-Id: I9eeb802b556ba86568cf41b456a4ceab4b896ef0

/**
* ClientMonitor subclass responsible for coordination of authenticatorId invalidation of other
* sensors. See {@link InvalidationClient} for the ClientMonitor subclass responsible for initiating
* the invalidation with individual HALs. AuthenticatorId invalidation is required on devices with
* multiple strong biometric sensors.
*
* The public Keystore and Biometric APIs are biometric-tied, not modality-tied, meaning that keys
* are unlockable by "any/all strong biometrics on the device", and not "only a specific strong
* sensor". The Keystore API allows for creation of biometric-tied keys that are invalidated upon
* new biometric enrollment. See
* {@link android.security.keystore.KeyGenParameterSpec.Builder#setInvalidatedByBiometricEnrollment}
*
* This has been supported on single-sensor devices by the various getAuthenticatorId APIs on the
* HIDL and AIDL biometric HAL interfaces, where:
* 1) authenticatorId is requested and stored during key generation
* 2) authenticatorId is contained within the HAT when biometric authentication succeeds
* 3) authenticatorId is automatically changed (below the framework) whenever a new biometric
* enrollment occurs.
*
* For multi-biometric devices, this will be done the following way:
* 1) New enrollment added for Sensor1. Sensor1's HAL/TEE updates its authenticatorId automatically
* when enrollment completes
* 2) Framework marks Sensor1 as "invalidationInProgress". See
* {@link BiometricUtils#setInvalidationInProgress(Context, int, boolean)}
* 3) After all other sensors have finished invalidation, the framework will clear the invalidation
* flag for Sensor1.
* 4) New keys that are generated will include all new authenticatorIds
*
* The above is robust to incomplete invalidation. For example, when system boots or after user
* switches, the framework can check if any sensor has the "invalidationInProgress" flag set. If so,
* the framework should re-start the invalidation process described above.
