Add api's to dvr_pose to retrieve data from sensord
Bug: 63683612
Test: Manually tested through VrCore cl/164799996.
To retrieve raw data from Tango, added below api's to dvr_api:
- dvrPoseClientGetDataReader
- dvrPoseClientDataCapture
- dvrPoseClientDataReaderDestroy
Note: These changes have already been reviewed in branch
oc-dr1-daydream-dev branch. See change 2729572.
Changes tested on Pixel XL with and without 02 rendering path. Daydream
Home rendering in VR Mode correctly. Pixel functioning as normal.
