net/mlx5e: Expose memory key creation (mkey) function

Expose mlx5e_create_mkey function, for future patches in the
macsec series to use.
The above function creates a memory key which describes a
region in memory that can be later used by both HW and SW.
The counterpart destroy functionality is already exposed.
