userspace/cuda: host golden-reference descriptor dump for the crash path
The host libcuda (570.211.01) has the identical engine-registration helper
instruction sequence (byte-pattern matched, host vaddr 0x454470 vs guest
0x453ef0). scripts/host_gdb_descriptor.sh runs cdt on the host under gdb and
prints the per-engine 6-dword registration record and the dispatch hook
target. Host registers a copy engine {3, 0xd, 4, 0xc5b5, 0x3e6, 3} and
cuCtxCreate succeeds; the guest registers GR {1, 1, 0, 0xc5c0, 0, 0} and
crashes - so the divergence is in the engine records the driver builds from
the emulated GSP static info engine table.
