genxml: Put append counter fields before MCS in RENDER_SURFACE_STATE on gen7
The pack header generation scripts can't handle the case where you have
two addresses in the same dword; they just take whatever is the last one.
This meant that the MCS address wasn't properly getting handled. Since we
don't care about append counters, we can just re-arrange the XML for now.
