Keep lightRevealEffect and lightRevealAmount up to date

- Update lightRevealAmount to the dozing amount immediately
when the lightRevealEffect is set in StatusBar (since
the PowerReveal and LiftReveal rely on dozing amount,
while the CircleReveal relies on timing)
- After the CircleReveal finishes, set the light reveal back
to the default LiftReveal
- Dump the light reveal effect to dumpsys for easier debugging

Test: manual (force AuthRippleController's KeyguardUpdateMonitorCallback
to be called before the BiometricUnlockController's callback)
