rtnl_link: check all struct rtnl_link_stats* and struct ifla_port_vsi types automatically

Move definitions of struct_rtnl_link_stats* and struct_ifla_port_vsi
types to a separate types/ header file.

* configure.ac (AC_CHECK_TYPES): Remove struct ifla_bridge_id,
struct ifla_port_vsi and struct rtnl_link_stats64.
(AC_CHECK_MEMBERS): Remove struct rtnl_link_stats.rx_nohandler and
struct rtnl_link_stats64.rx_nohandler.
* rtnl_link.c: Include "types/rtnl_link.h".
[HAVE_LINUX_IF_LINK_H]: Remove.
[HAVE_STRUCT_RTNL_LINK_STATS_RX_NOHANDLER,
HAVE_STRUCT_RTNL_LINK_STATS64_RX_NOHANDLER, HAVE_STRUCT_IFLA_PORT_VSI]:
Remove static_assert checks.
(struct_rtnl_link_stats, struct_rtnl_link_stats64,
struct_ifla_port_vsi): Move to ...
* types/rtnl_link.h: ... new file.
(struct_ifla_bridge_id): New typedef.
