Device Idle: Android wear support

- Provide config param: autoPowerModeThresholdAngle allowing us to
  adjust the tilt threshold on a per-device basis.
- Provide config param: autoPowerModePrefetchLocation allowing us to
  skip location prefectching on a per-device basis.
- Provide config param: autoPowerModeAnyMotionSensor allowing us to
  use a device-specific sensor on to detect additional types of movement
  that would trigger exiting device idle.
- PRovide config param: autoPowerModePreferWristTilt allows us to use
  the wrist tilt detector in lieu of the SMD if an anymotion sensor
isn't specified.
- Allow DeviceIdleController to use wrist tilt sensors if the device provides
  one.
- Use wrist tilt or SMD when an "any motion" sensor isn't available.
- Fix bugs where DeviceIdleController would crash on devices that did
  not have a location and/or gps provider (some android wear devices).
