Static multiwindow for large screens in Auto.
This change enables setting a persistent docked application
at compile time such that it will always be on screen. This
can be leveraged by an OEM to include their app which can
switch between different metadata based views, like the next
turn, the currently playing song or any notifications.
One pager: go/aae-sysui-o
TODO:
- Customize the animations.
- Recents shows up for a brief moment on the first activity launch,
this needs to be fixed.
