Add a bit to bubble info to indicate if the app badge should be shown

For the "anything can bubble" prototype we show the app icon as the
bubble icon and the extra badge looks weird. Launcher will use this
bit to hide the badge in this scenario.

Flag: com.android.wm.shell.enable_bubble_anything
Test: manual - add an app bubble to bubble bar, observe it's not
               badged (with launcher CL)
