Jason Gerecke d522074232 Support unique calibration per orientation
Updates the format of the calibration XML to store the Surface rotation
that a specific calibration applies to. Also updates the API to require
a rotation value for get/set, and has the native framework supply this
according to the current rotation whenever it changes.
