Subject: [PATCH 09/12] Add taskbar TAPL tests

- Added TAPL objects to support TAPL tests for taskbar features
- Added tests for major taskbar features: hiding/showing the taskbar, opening all apps, lauching apps and app deep shortcuts from the taskbar/all apps page, launching apps and app deep shortcuts in splitscreen
- These tests should only run for large devices

Design: go/taskbar-tapl-tests
Test: ran tests locally with invalid configurations and remotely
Bug: 215218813
Change-Id: I3c28c339707467414aa47fa633f87fa0c1fdee57

Subject: [PATCH 11/12] Launcher side implementation of gesture seekable back
 to home animation.

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.

+ * This animation is used only for apps that enable back dispatching via
