cameraservice: Make getSessionCharacteristics accessible earlier
The current implementation of getSessionCharacteristics forced Camera2
to open a corresponding CameraDevice. However, there is no technical
limitation that prevents getSessionCharacteristics from being
accessible before an openCamera call.
This CL moves the getSessionCharacteristics to be a function in
ICameraService instead of ICameraDeviceUser which allows camera2
to call getSessionCharacteristics before calling openCamera
for a given device.
