refactor: simplify preseed configuration and nvidia setup

- Remove development packages (clang, lld, llvm, libdw-dev, dkms) from default installation
- Delete late_custom_amd.sh script as it's no longer needed
- Simplify late_custom_nvidia.sh to focus only on CUDA and nvidia-open installation
- Comment out nvidia script execution in preseed for optional manual use
