Adjust screen off animation behavior for MinMode

When MinMode is active, `DozeParameters` now enables "Always On" and
forces `shouldAnimateDozingChange` to true. In
`UnlockedScreenOffAnimationController`, MinMode triggers a `LiftReveal`
effect, uses a shorter animation duration, and skips the delayed showing
of the AOD UI.
