1/n: Add ClientMonitors for authenticatorId invalidation

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.
