Launcher side implementation of gesture seekable back to home animation.

Browse Source 
This is a two part animation. The first part is an animation that tracks gesture location to scale and move the leaving app window. Once the gesture is committed, the second part takes over the app window and plays the rest of app close transitions in one go.

This animation is used only for apps that enable back dispatching via {@link android.view.OnBackInvokedDispatcher}. The controller registers an {@link IOnBackInvokedCallback} with WM Shell and receives back dispatches when a back navigation to launcher starts.

Apps using the legacy back dispatching will keep triggering the WALLPAPER_OPEN remote transition registered in {@link QuickstepTransitionManager}.

Bug: b/195946584
Test: m -j
Test: Swipe back to home on pre-T and T apps, at different life cycle
stages.
