kms: Have the device impl open device files themself
This changes the way the KMS backends load; if we're headless, we always use the dummy one and fail otherwise; in other cases, we first try the atomic backend, and if that fails, fall back on the simple one. The aim for this is to have the impl device open and close the device when needed, using the device pool directly. Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1828>
