tools/debug: add read-only GMMU/pdb scanners for live guest RAM
pdb_scan_gmmu walks the GP10X/VER2 GMMU page-table format (PD3/PD2/PD1/
PD0/PT, 16-byte dual PD0 entries, sys/vidmem apertures) and pdb_scan is
the x86-64 index cross-check. Both map the QEMU pc.ram file correctly
for the 2 GiB low + high-RAM q35 layout and are strictly read-only.
Used to prove the ring page/VA and pdb chains in CONT.435/436.
