net/mlx5e: Advertise mlx5 ethernet driver updates sk_buff md_dst for MACsec

commit 39d26a8f2efcb8b5665fe7d54a7dba306a8f1dff upstream.

mlx5 Rx flow steering and CQE handling enable the driver to be able to
update an skb's md_dst attribute as MACsec when MACsec traffic arrives when
a device is configured for offloading. Advertise this to the core stack to
take advantage of this capability.
