Phase 3: RPC Handler Completion

- Enhanced gsp_rpc_client.c with proper emulation implementations:
  - ALLOC/FREE: VRAM allocation tracking with host page allocation and DMA mapping
  - MAP/UNMAP: GPU VA mapping management
  - PIN/UNPIN: DMA address retrieval for pinned pages
  - SCHEDULE/YIELD: Local workqueue-based scheduling
  - NOTIFY: Callback registration for async events
- Added emulation function declarations to gsp_rpc_client.h
- Exported nv_vgpu_simple_mapping struct in memory.h for cross-file use
- Updated RPC handlers to use gsp_rpc_emulation_is_enabled() accessor
- All 12 RPC types now have functional emulation fallbacks
