This change fixes a bug when using just-in-time CDI spec generation for the
NVIDIA Container Runtime for specific devices (i.e. not 'all').
Instead of unconditionally using the default nvsandboxutils library -- leading
to errors due to undefined symbols -- we check whether the library can be
properly initialised before continuing.

This change includes the usage of Sandboxutils GetDriverVersion API to
retrieve the CUDA driver version. If the library is not available on the
system or the API call fails for some other reason, it will fallback to
the NVML API to return the driver version.

A driverRoot defines both the driver library root and the
root for device nodes. In the case of preinstalled drivers or
the driver container, these are equal, but in cases such as GKE
they do not match. In this case, drivers are extracted to a folder
and devices exist at the root /.
The changes here add a devRoot option to the nvcdi API that allows the
parent of /dev to be specified explicitly.

CDI generation modes such as management and wsl don't require
NVML. This change removes the top-level instantiation of nvmllib
and replaces it with an instanitation in the nvml CDI spec generation
code.
