utils: tuning: libtuning: Implement the core of libtuning

Implement the core of libtuning, our new tuning tool infrastructure. It leverages components from raspberrypi's ctt that could be reused for tuning tools for other platforms. The core components include: - The Image class - libtuning (entry point and other core functions) - macbeth-related tools, including the macbeth reference image - utils Signed-off-by: Paul Elder <paul.elder@ideasonboard.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
