This allows to export the type in BTF and so in the automatically generated vmlinux.h. It will also add some static checks on the users when we change the ll driver API (see not below). Note that we need to also do change in the ll_driver API, but given that this will have a wider impact outside of this tree, we leave this as a TODO for the future.
