Returns tracking state reading based on the specified absolute system time.
Pass an absTime value of 0.0 to request the most recent sensor reading. In this case
both PredictedPose and SamplePose will have the same value.
ovrHmd_GetEyePose relies on this internally.
This may also be used for more refined timing of FrontBuffer rendering logic, etc.
