Add a bubble option to launcher long press menus

- Add a launcher "system shortcut" to bubble deep shortcuts or apps
- For shortcuts, save the shortcut info to use to produce the bubble
- Add an interface so that the system shortcut can call through to
  sysui proxy

Flag: com.android.wm.shell.enable_bubble_anything
Test: manual - enable the flag and try to bubble a shortcut via the
               longpress menu on launcher
             - try bubbling an app on launcher
             - try bubbling an app from the taskbar
