freedreno/ir3: move emit_const to ir3
Details of the cmdstream packets are different between a3xx and a4xx, but the logic about the layout of const registers is the same, as that is dictated by the ir3 shader compiler. So rather than duplicating logic that is tightly coupled to ir3 between a3xx and a4xx, move this into ir3 and use per-generation callbacks for to build the cmdstream packets. This should make it easier to pass additional const regs (such as for transform feedback). And it also keeps the layout internal to ir3 in case we want to make the layout more dynamic some day.
