Add rotary support to the nav bar and HUN.

Add a FocusParkingView to the navigation bar and the heads-up
notification window. Add a dependency on the Chassis UI library.
Make the nav buttons have a blue background, or whatever color
the OEM specifies for the focus highlight.

Test: atest com.android.systemui.car.navigationbar.CarNavigationButtonTest
