net/mlx5: Support matching on l4_type for ttc_table

Replace matching on TCP and UDP protocols with new l4_type field which
is parsed by steering for ttc_table. It is enabled by the
outer_l4_type or inner_l4_type bits in nic_rx or port_sel flow table
capabilities and used only if pcc_ifa2 bit in HCA capabilities is set.
