Introduce INPUT_CONSUMER permission for InputConsumer

Add the permission protect to createInputConsumer/destoryInputConsumer
in WindowManagerService to prevent it is possible for an app to consume
all the touch events and deny them from even reaching System UI.

Also fix the wallpaper inputconsumer should only show when we found a
visible wallpaper window.

Also limit 'createInputConsumer' to the defined types.
