Updates to app to icon animation, and turns on ADAPTIVE_ICON_WINDOW_ANIM flag.

- getFirstMatchForAppClose now only looks at the current page, since switching
  pages is disruptive and the animation for app closing to an icon on a
  different page is unclear.
- Searches for package name and user id (in case of work profile app)
  instead of component name to handle shortcuts and trampoline activities.

- Adaptive icon background drawable is now always centered

- Fix crash that occurs when ADAPTIVE_ICON_WINDOW_ANIM is off. We were trying
  to set FolderAdaptiveIcon as the background drawable. Simplest solution is
  to not use folder as a search criteria when the flag is off.

- Similar to DragView, FloatingIconView now uses BubbleTextView icon when
  adaptive icon support is not available. This handles legacy-treated apps.
