bpf: remove struct bpf_map_type_list
There's no need to have struct bpf_map_type_list since it just contains a list_head, the type, and the ops pointer. Since the types are densely packed and not actually dynamically registered, it's much easier and smaller to have an array of type->ops pointer. Also initialize this array statically to remove code needed to initialize it. In order to save duplicating the list, move it to the types header file added by the previous patch and include it in the same fashion.
