net/mlx5: Add VHCA RX flow destination support for FW steering
Introduce MLX5_FLOW_DESTINATION_TYPE_VHCA_RX as a new flow steering
destination type.
Wire the new destination through flow steering command setup by mapping
it to MLX5_IFC_FLOW_DESTINATION_TYPE_VHCA_RX and passing the vhca id,
extend forward-destination validation to accept it, and teach the flow
steering tracepoint formatter to print rx_vhca_id.
