refactor car libs

- all car libs moved to car-libs (not libvehiclenetwork as this is not
  car lib)
- top level car library is just car which pulls car-core and car-ui.
- car apps should include car-libs/car.mk to use resource for car-ui.
- apps only sing car-ui can include car-libs/car-ui/car-ui.mk.
