net/mlx5: Expose IP-in-IP TX and RX capability bits
Expose FW indication that it supports stateless offloads for IP over IP
tunneled packets per direction. In some HW like ConnectX-4 IP-in-IP
support is not symmetric, it supports steering on the inner header but
it doesn't TX-Checksum and TSO. Add IP-in-IP capability per direction to
cover this case as well.
Note: only if both indications are turned on, the global
tunnel_stateless_ip_over_ip is on too.
