This change adds a new discoverer for Sandboxutils to report the file
system paths and associated symbolic links using GetGpuResource and
GetFileContent APIs. Both GPU and MIG devices are supported. If the
Sandboxutils discoverer fails, the NVML discoverer is used to report
the file system information.

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.

This change adds manual wrappers around the generated bindings to make
them into more user-friendly APIs for the caller. Some helper functions
are also added.
The APIs that are currently present in the library and implemented here
are:
nvSandboxUtilsInit
nvSandboxUtilsShutdown
nvSandboxUtilsGetDriverVersion
nvSandboxUtilsGetGpuResource
nvSandboxUtilsGetFileContent

This change adds the internal bindings for Sandboxutils, some of which
have been automatically generated with the help of c-for-go. The format
followed is similar to what is used in go-nvml. These would need to be
regenerated when the header file is modified and new APIs are added.

This change adds a script and related files to generate the internal
bindings for Sandboxutils library with the help of c-for-go.
This can be used to update the bindings when the header file is modified
with reference to how they are generated with the Makefile in go-nvml.

With the move to dependabot to udpate the libnvidia-container
submodule it is no longer required to have checks in place that
ensure that this is up to date when building.
In addition when re-building old commits in CI, for example we explicitly
do NOT want to have this check.

This change enables opt-in (off-by-default) features to be opted into.
These features can be toggled by name by specifying the (repeated)
--opt-in-feature command line argument or as a comma-separated list
in the NVIDIA_CONTAINER_TOOLKIT_OPT_IN_FEATURES environment variable.

This change adds an include-persistenced-socket flag to the
nvidia-ctk cdi generate command that ensures that a generated
specification includes the nvidia-persistenced socket if present on
the host.
Note that for mangement mode, these sockets are always included
if detected.

This change ensures that the internal CDI representation includes

This changes skips the injection of the nvidia-persistenced socket by
default.
An include-persistenced-socket feature flag is added to allow the
injection of this socket to be explicitly requested.

This change updates the create-symlinks hook to check whether
link paths resolve in the container's filesystem. In addition
the executable is updated to return an error if a link could
not be created.
