camera2: Add CameraDeviceSetup

This patch adds a CameraDeviceSetup class within CameraDevice
class which provides access to a limited subset of CameraDevice
class methods without requiring the apps to pay the latency
cost of opening a full CameraDevice.

In addition to functions parallel to CameraDevice, it also
provides a utility method to open the CameraDevice, effectively
serving as a proto CameraDevice.
