config: gather options for dlopen mlx dependency
Rename options CONFIG_RTE_LIBRTE_MLX4_DLOPEN_DEPS and CONFIG_RTE_LIBRTE_MLX5_DLOPEN_DEPS to a single option CONFIG_RTE_IBVERBS_LINK_DLOPEN. Rename meson option enable_driver_mlx_glue to ibverbs_link. There was no good reason for setting a different link option for mlx4 and mlx5. Having a single common option makes it easier to understand and unify make and meson systems.
