Put taskbar all apps in separate overlay window and stash taskbar.

All apps should display below system UI components such as the notification tray and power menu, so an overlay window is more appropriate. As a result, all apps has a separate window activity context, but some properties are delegated to the taskbar activity context. Taskbar should also be stashed while all apps is open.
