net/mlx5: Implement new destination type TABLE_TYPE

Browse Source 
Implement new destination type to support flow transition between
different table types.
e.g. from NIC_RX to RDMA_RX or from RDMA_TX to NIC_TX.
The new destination is described in the tracepoint as follows:
"mlx5_fs_add_rule: rule=00000000d53cd0ed fte=0000000048a8a6ed index=0 sw_action=<> [dst] flow_table_type=7 id:262152"
