repo: Untrack binaries/vendor/wrapper layers, add .gitignore + NVIDIA patches

Restructure for clean mirroring to git.vgpu.io/open-iov.git:

- Untrack GSP firmware blobs and decompiled output (firmware/**/*.bin,
  firmware/**/decompiled/) - large, license-restricted NVIDIA binaries.
  Analysis scripts, docs, and address maps remain tracked.
- Untrack nvidia-open-gpu-kernel-modules submodule; our delta against
  upstream tag 610.57.04 is now tracked as a patch series in
  patches/nvidia/ and applied by install.sh after cloning.
- Untrack kernel build artifacts (*.o, *.ko, Module.symvers, ...).
- Untrack Ghidra project databases (*.rep/, *.gpr) - scripts remain.
- Untrack VM images (*.iso, *.img, *.qcow2) and compiled helper binaries.
- Drop git-lfs (.gitattributes) - no large objects remain in git.
- Local QEMU-wrapper layers (scripts/vgpu_vm.py,
  qemu_control.py, qemu_harness.sh) are gitignored: the repo is
  hypervisor-management neutral (libvirt, raw QEMU all work).

All files remain on disk; only git tracking changes. No source code
modified.

+# Open-IOV .gitignore
+#
+# Goals:
+#   - No large binary objects in git (firmware blobs, VM images, Ghidra DBs)
+#   - No build artifacts
+#   - No vendor trees (NVIDIA OpenRM is pulled + patched by install.sh)
+#   - No local QEMU-wrapper stacks (/, guest communication daemon) - the repo is
+#     hypervisor-management neutral (works with libvirt, , raw QEMU, ...)
