This change adds functionality to generate CDI specifications for all devices detected on the system. A specification containing all GPUs and MIG devices is generated. All libraries on the host ldcache that have an NVIDIA Driver Version suffix are included as are the required binaries and IPC sockets. A hook (based on the nvidia-ctk hook subcommand) to update the ldcache in the container for the libraries being injected is also added to the CDI specificiation.
