v4l2: camera_proxy: Store v4l2_pix_format instead of v4l2_format
The V4L2 compatibility layer only uses the fmt.pix field of curV4L2Format_. There's no need to cache the full v4l2_format, store v4l2_pix_format only and rename the member variable from curV4L2Format_ to v4l2PixFormat_. While at it, group the V4L2-related member variables together in the V4L2CameraProxy class.
