vgsp: contiguous shadow PTEs for multi-page GR buffers (R4)
The mail launch's param buffer spans two pages but the QMD names only the
base page. The second page has no pointer word, so the Tier-2 shadow path
skipped it and the launch was refused. Map a page with no pointer word that
is contiguous with the previous shadow-mapped page into the next PTE of the
same 128 B fetch line (each line covers up to 16 consecutive 4 KB pages),
keeping the rewritten base-pointer buffer contiguous for the engine.
