vgsp: m86 - sticky gsp_phys_rmcall_gr_override_hex module parameter
The override blob can now be supplied at load (hex string, <= 1 page) and is
parsed at the first forwarded launch, so the minimal-kernel experiment no
longer depends on a debugfs write racing the guest's launch. Also observed in
the m86 attempt: after many failed launches the forwarded ring desynced
(USERD GP_PUT rewound to 1 while the engine's GP_GET was 513; IQ2M sentinel
intact, no FE fetch) - a fresh boot is required per experiment.
