c90211e070 Log explicitly requested runtime mode 
For users running the nvidia-container-runtime it would be useful
to determine the runtime mode used from the logs directly instead
of relying on other log messages as signals. This change ensures
that an explicitly selected mode is also logged instead of only
when mode=auto.

833254fa59 Support CDI devices as mounts 
This change allows CDI devices to be requested as mounts in the
container. This enables their use in environments such as kind
where environment variables or annotations cannot be used.

1dc028cdf2 Add UsesNVGPUModule info function 
This change adds a UsesNVGPUModule function that checks whether the nvgpu
kernel module is used by NVML. This allows for more robust detection of
Tegra-based platforms where libnvidia-ml.so is supported to enumerate the
iGPU.

c77e86137e Add version output to CLIs 
This change adds version output to the nvidia-continer-runtime,
nvidia-container-toolkit, and nvidia-ctk CLIs. The same version
is used in all cases and includes a version string and a git
revision if set.

The construction of the version string mirrors what is done in runc.
