vgsp: m106 - pre-install the data PT window pool in stage 3 (pre-commit)
Post-commit UPDATE_PDE_2 installs are accepted (status 0x0) but ineffective
(m94's scratch windows, m101-m105's reloc windows: the SM never resolves
them), while the stage-3 ctx-window installs are honoured. Add a fixed
32-window pool at GSP_PHYS_RMCALL_VA_GR_DATA_BASE (0x100000000 + k<<21,
inside the server-managed region), each backed by a module PT page
installed through UPDATE_PDE_2 during stage 3; the engine data map then
only writes leaf PTEs into those fresh PT pages at launch (the P6b-proven
'direct leaf write into a walker-installed fresh table' pattern). The mail
injection uses the reserved last window (k=31); service data windows cap
at 31 and use the same fixed layout.
