Create ViewModel for QS compose and a basic fragment

This is the first iteration of integrating the new QS into compose. It
achieves the following:

* Fragment integrated into NotificationShade
* Shows QQS when collapsed and QS when expanded
* Has all elements (tiles, brightness, footer, edit mode).
* Tiles and footer are clickable. Long click on tiles is broken
  (b/358376794).
* Tests that show qqs/qs pass.

This creates a skeleton viewmodel to which calls will be forwarded from
the fragment (QS interface) that come from NPVC. That way it's
transparent for the current NPVC.

Missing:

* Animations and transitions
* Most calls into QS are Noop.
* No final UI (as that will be handled in the components).
