Change work profile switch to floating button

This is an initial CL to replace the old switch button. This CL only
focusses on introducing the new floating action button:
* Remove the work profile switch
* Add extended floating action button for switching between profiles
* Hide the button in preview mode and when an item is selected
* Hide the button in Album photos view

More specifications will follow soon
