vc4: Pack the unorm-packing bits into a src MUL instruction when possible.
Now that we do non-SSA QIR instructions, we can take a NIR SSA src that's
only used by the unorm packing and just stuff the pack bits into it.
total instructions in shared programs: 98136 -> 97974 (-0.17%)
instructions in affected programs: 4149 -> 3987 (-3.90%)
