radv: Don't declare ngg_gs_state when there is no API GS.

Browse Source 
This shader arg is only used when the pipeline has API GS,
so it is useless to declare it otherwise.

Also remove unused code from radv_declare_shader_args.
NGG is handled by the GS code path so these were never
actually used.
