AuthRipple should always animate lightReveal on auth

- AuthRipple animates light reveal even when the
device is going to sleep.
- If another light reveal effect has taken over, then
the auth ripple should immediately cancel its animation
so that subsequent authentications within that time aren't
taken over by a stale animator (and so the stale animator
isn't needlessly animating)
- Before setting the reveal effect to the circle effect,
immediately reset the revealAmount to 0 so we start with
a clean black screen rather than flashing before resetting.
- Add reveal amount to the trace (which will be an int value between
0 and 100, where 0 represents revealAmount=0 and 100 is revealAmount=1f)

Test: manually authenticate with rear FP when device is going to sleep +
repeat
