[camera_android_camerax] Modify availableCameras to set camera name to Camera2CameraInfo.getCameraId #147545
Description
Currently, the camera_android_camerax plugin sets the camera name of the available cameras (retrieved via availableCameras) to a random camera name and ID -- see source. To maintain feature parity with camera_android, we should use the value retrieved from Camera2CameraInfo.getCameraId.
