Preload overview after unfold
Before this change, the configChange was processed when launcher becomes visible. However, this happened during animations (e.g. swipe to home after unfold to app).
With this change, the onConfigChange received by TIS (so, it's received also if the activity is not visible), is used to preload overview, moving a ~100ms block to unfold instead of during the animation.
Bug: 294352799
Test: recorded a perfetto trace and checked jank decrease
