Adds two ABI handlers exercised by Nsight Systems / CUPTI GPU profiling: - NV01_MEMORY_DEVICELESS (0x90ce) allocation class, a generic memory class used (among other things) to back CUPTI's event record buffers. Handled like the other NV01_MEMORY_* classes (NV_MEMORY_ALLOCATION_PARAMS, and NV_MEMORY_ALLOCATION_PARAMS_V545 from 545.23.06); added to the base ABI with compute/utility gating. - NV2080_CTRL_CMD_GR_GET_SM_ISSUE_RATE_MODIFIER_V2 (0x2080123c), a GR info query introduced in 575.51.02 (bisected via tools/nvidia_driver_differ), registered at that lineage node with the same compute/utility gating as the existing V1 handler. Validated with tools/nvidia_driver_differ.
