cameraservice: Log session index
For tracking camera performance, it is helpful to know the order in
which camera sessions are created.
This CL adds a sessionIndex field to CameraSessionStats which tracks
the order in which sessions were created. This field is logged by
ICameraServiceProxy.
Bug: 236318755
Test: CtsCameraTestCases pass. No functional change.
