Stop animation when screen times out and the user turns on the phone.

When screen turns on, display off sleep token and keyguard sleep token
are both removed. However it's not deterministic which one is removed
first, so we have to take care both cases.

Test: atest KeyguardTransitionTests and manual.
  1. set lock mode to none (keep showing Settings activity)
  2. wait until the screen times out
  3. tap screen to turn on the screen
  4. verity no animation is applied on the Settings activity
