[Predictive Back] Fix predictive back swipe on task bar all apps [1/n]

Browse Source 
For taskbar all apps, the background scrim is child view of AbstractSlideInView, thus scaling AbstracSlideInView during PB swipe will scale down background scrim. There is no need to re-apply scale effect on background scrim separately.

Bug: 327490078
Flag: aconfig com.android.launcher3.enable_predictive_back_gesture TEAMFOOD
Test: manual
