add skeleton for car service and car api
- car service: system uid with system signature, starts in PRE_BOOT_COMPLETED
- added minimal skeleton implementation for proof of convept for several key ideas:
Car api, CarServiceLoader interface, CarActivity abstraction
- Also adding CarSensorManager/Service for defining flow in HAL initialization.
