mlx5 experimental API's

The Mlx5 device has these experimental API's.

EXPERIMENTAL {
	global:

	# added in 20.02
	rte_pmd_mlx5_get_dyn_flag_names;
	# added in 20.11
	rte_pmd_mlx5_sync_flow;
	# added in 22.03
	rte_pmd_mlx5_external_rx_queue_id_map;
	rte_pmd_mlx5_external_rx_queue_id_unmap;
	# added in 22.07
	rte_pmd_mlx5_host_shaper_config;
	rte_pmd_mlx5_external_sq_enable;
	# added in 23.03
	rte_pmd_mlx5_flow_engine_set_mode;
};

The intention of DPDK stable API policy is that experimental flag is temporary. Which of these can be marked as stable (or should be removed).
