Blink's layout tests mock the generic sensors impl client-side in JS, so this is blocked from landing until  crbug.com/689385  is fixed.

Port device_generic_sensor to be hosted in Device Service.

Generic_sensor is currently hosted in RenderFrameHostImpl, this CL move
it to be hosted in Device Service.

The exsiting dependencies from //content/ to //device/generic_sensors are:
1) Generic_sensor_browsertest. I will replace browsertest by a device service
   test in next CL.
2) JNI registry and APK packaging. It is easy to remove those deps when moving
   //device/generic_sensor files into //service/device.
