radv: Enable NGG wave ID for mesh shader scratch ring.

Browse source 
This wave ID is used to address the scratch ring, so it should be
enabled when the scratch ring is used.

Note: the naming is confusing here, as this ID is actually the same
accross the whole workgroup. (It would be more appropriate to call
it workgroup ID instead.)
