net/mlx5: Expose new packet reformat capabilities 

Expose new abilities when creating a packet reformat context.

The new types which can be created are:
MLX5_REFORMAT_TYPE_L2_TO_L2_TUNNEL: Ability to create generic encap
operation to be done by the HW.

MLX5_REFORMAT_TYPE_L3_TUNNEL_TO_L2: Ability to create generic decap
operation where the inner packet doesn't contain L2.

MLX5_REFORMAT_TYPE_L2_TO_L3_TUNNEL: Ability to create generic encap
operation to be done by the HW. The L2 of the original packet
is dropped.
