Apply Grpc Client to current VHal Implementation

Test: tested on Cuttlefish VM

 - Use virtualization HAL implementation, device/google/cuttlefish/shared/auto/device.mk, PRODUCT_PACKAGES:
      remove android.hardware.automotive.vehicle@2.0-service
      add:
        android.hardware.automotive.vehicle@2.0-virtualization-service
        android.hardware.automotive.vehicle@2.0-virtualization-grpc-server

 - configure the server CID and port, add the following device/google/cuttlefish/shared/config/init.vendor.rc:
        setprop ro.vendor.vehiclehal.server.cid 3
        setprop ro.vendor.vehiclehal.server.port 9210
 - Build and Launch cuttlefish VM
        m && acloud create --boot-timeout 3600 -vv --local-instance --local-image
 - VHAL should work as normal, see tests in ag/9693857
