This change creates an nvidia-cdi-hook binary for implementing CDI hooks. This allows for these hooks to be separated from the nvidia-ctk command which may, for example, require libnvidia-ml to support other functionality. The nvidia-ctk hook subcommand is maintained as an alias for the time being to allow for existing CDI specifications referring to this path to work as expected.
