Evan Lezar d37c17857e Add nvidia-ctk info generate-cdi command
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.
