camera3: Add physical camera id field in capture result
- Add an array of physical camera ids and metadata when physical
cameras are requested within a logical multi-camera.
- Physical camera ids and metadata are only necessary for the final
capture_results, not the partial result.
- Physical camera ids and metadata must not be populated if no physical
camera is requested.
Test: Compile
