Subject: Phase 1: Add GSP Emulation Engine (host-side)

- New kernel/gsp_emulation.h: GSP emulation context and API
- New kernel/gsp_emulation.c: Per-mdev emulation thread with:
  - Adaptive polling of doorbell at BAR0+0x110C00
  - Shared memory RPC processing (4KB at BAR0+0x1000)
  - Dispatch for all 12 RPC types via firmware-decompiled handlers
  - MSI-X completion interrupt injection via eventfd
  - Statistics tracking (processed/failed RPCs, latency)
- Modified kernel/main.c: Integrate gsp_emu_init/cleanup in device lifecycle
- Modified kernel/Makefile: Add gsp_emulation.o to build
- Modified kernel/gsp_rpc_client.h: Export gsp_rpc_emulation_set/is_enabled
