vgsp: alias-map indirect high-VA GR pages and fix up shadow pointers

The mail kernel's output buffer has no QMD pointer word; the engine reaches
it through a pointer inside the parameter bank, so the Tier-1 refusal at its
high VA killed the launch. Alias-map such a page's guest HPA at a fresh
ladder line and rewrite every matching 8-byte pointer inside the shadowed
copy pages (param/program) to the alias, so engine writes land in the
guest's own page and the guest's DtoH sees them.
