Fix scrim alphas getting reset during the bouncer/alt-bouncer->gone transition

[Alt]Bouncer -> Gone transition falls into these buckets:
  1. Swipe up from lockscreen -> bouncer -> gone
     - Lockscreen dismiss animation plays from the bouncer and device is entered.
  2. Lockscreen notif click -> bouncer -> gone,
     - Bouncer hidden and dismiss animation plays from lockscreen
     - willRunDismissFromKeyguard is true
  3. Expand shade, click on something -> bouncer -> gone
     - Bouncer hidden and dismiss/launch animation plays from lockscreen (expanded shade)
     - willRunDismissFromKeyguard && isShadeOpen is true
  4. Expand shade, do inline reply or edit QS -> bouncer -> gone
     - Bouncer hidden, no dismiss animation and expanded shade is visible after
     - willRunDismissFromKeyguard is false and leaveShadeOpen is true

Summary of changes:
 - Update bouncer to gone flows to handle these 4 scenarios when bouncer blur is enabled and shade blur is enabled/not enabled
 - Add additional logging info to ScrimController for debugging.
