Add AIDL version of vehicle hal

- This is still under development but will replace HIDL version later.
- It will become stable later when all necessary features are ready.
- This CL translated HIDL into AIDL as it is. More changes will be added later.
- Most code was generate from hidl2aidl:
  $ hidl2aidl -o tmp android.hardware.automotive.vehicle@2.0
- translate_vehicle_props.py types.hal to generate VehicleProperty enum.
- added @utf8InCpp for all String
