Add work profile footer in work tab

Screenshot(work mode is on): https://hsv.googleplex.com/6279751685636096
Screenshot (work mode is off): https://hsv.googleplex.com/6279751685636096

TODO:
It is just the UX bit, once the platform change is in, we should then
consume the new API to
1. Turn on / off work mode
2. Get the organization name and set the textview accordingly.
