Wait for systemui udfps overlay ready to show settings udfps enroll view.

Previously, we show settings's udfps enroll animation view (the fingerprint icon and progress view) once the FingerprintEnrollEnrolling is shown.
However, touch events have to wait for systemui's udfps overlay to be valid. This CL lets settings's udfps enroll view wait for systemui's overlay.
1. Sets udfps enroll animation view's default visibility Gone.
2. Propagates FingerprintManager#onUdfpsOverlayShown to
   FingerprintEnrollEnrolling and when it's called, set the enroll view
   visible.

Besides, this CL renames onPointerDown() and onPointerUp() with Udfps.
