vgsp: add golden-replay mode 25 (captured client construct + atomic 9-entry promote)
Ladder mode 25 reproduces the real 570.144 host client's golden-image
construct on the golden replay handles: captured channel shape (flags
0x00200320, hObjectBuffer 0, gpFifoOffset 0, gpFifoEntries 0x20,
engineType 1, host memdesc substitutions), a single atomic 9-entry
GPU_PROMOTE_CTX on the golden channel (MAIN id0 and PATCH id2 combined,
ids 3/4/5/6 VA-only globals, ids 9/10/11 FECS/PRIV/UNR combined), then
the TURING_A 3D object. The golden VAS/channel/3D object stay alive and
the existing V6 FWCLIENT promote follows on the golden-initialized
GR-instance state; a failed golden step aborts with no retry and no
follow-up promote. The captured VAS COPY_SERVER_RESERVED_PDES control is
implemented gated (fwclient mask bit 8, zero-level no-op form) because
its level PAs are server-internal. Mode clamp/name/help extended to 25;
modes 1-24 unchanged.
