libcamera: v4l2_subdevice: Update to the new kernel routing API
The subdev embedded data support series includes a change to the VIDIOC_SUBDEV_G_ROUTING and VIDIOC_SUBDEV_S_ROUTING ioctls that impacts the userspace API. Update to the new API, while preserving backward compatibility to ease the transition. Document the backward compatibility to only be supported for two kernel releases. As the routing API isn't enabled in any upstream kernel yet, users of the API need kernel patches, and are expected to be able to upgrade quickly.
