IScnObjCallback Weak Function Ordering in d_a_obj_appear_bridge

[elijah-thomas774]

It was found that the function ordering of the weak nw4r::g3d::IScnObjCallback virtual functions appears in an odd order.
It would be nice to revisit when more info is found / g3d is ported in

    // The vtable order is            dtor, World,   Mat,  View,   Opa,   Xlu
    // and the emitted order is       dtor,   Xlu,   Opa,  View,   Mat, World
    // but the order in the binary is dtor,   Xlu,   Opa,  Mat,  World,  View

Changing stage_render_stuff.h

#include "d/a/obj/d_a_obj_base.h"
#include "m/m3d/m_scnleaf.h"
#include "nw4r/g3d/g3d_scnobj.h"

+class temp : public nw4r::g3d::IScnObjCallback {
+    temp() {}
+    virtual void ExecCallback_CALC_WORLD(nw4r::g3d::ScnObj::Timing, nw4r::g3d::ScnObj *, u32, void *) override {}
+};
+
+class temp0 : public nw4r::g3d::IScnObjCallback {
+    temp0() {}
+    virtual void ExecCallback_CALC_VIEW(nw4r::g3d::ScnObj::Timing, nw4r::g3d::ScnObj *, u32, void *) override {}
+};

class dScnCallback_c : public nw4r::g3d::IScnObjCallback {

This will emit the nw4r::g3d::IScnObjCallback functions in the correct order.

Holding off on implementing this change because there is no current real reason to have code written like this.
