Camera: Add MOTION_TRACKING capability/intent, and lens poseReference

- Add MOTION_TRACKING capability, which defines a camera with accurate
  lens calibration values, accurate timestamps relative to the
  inertial sensors, and ability to limit exposure time to 20ms.
- Add MOTION_TRACKING capture intent, which limits AE to 20ms max
  exposure.
- Add android.lens.poseReference for supporting gyroscope-centered
  lens calibration data for MOTION_TRACKING.
- Remove accidental typo in session parameter docs

Test: Builds, hidl-gen/hidl-doc are happy with the HIDL output
