Frameworks: fix qs and notification shade toggle on expanded desktop

If expanded desktop is enabled and statusbar hidden the toggle does not force
the statusbar to show before it pulls down the shade

fix it with just requesting the the statusbar to show up before we actually
peform the action

Frameworks: Add user protection and pie/navbar toggle to SlimActions

Add drawables for it and enable it for navbar, pie, hwkeys
and GlobalMenu and whatever other shorcutfeature want to have it

Keep the user save and do not allow to disable all navigations to keep
the device usable. User will be notified

In Settings user get the choice to enable the other navigation method. Of course
only on navbar devices due that hw key devices always have a working navigation

PS
- extend it and make the actions on global menu as toggle action
  to show on/off and reflect it on the icon as well
