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.

Changes since combined RFC:
- Drop -ENOTTY special handling in getRouting()
- Preserve backward compatibility for a couple of kernel releases.
