Since we expect .so.1 symlinks to be created by ldconfig, we don't
explicitly request these. This change removes the creation of
a libnvidia-allocator.so.1 -> libnvidia-allocator.so.RM_VERSION symlink
through the create-symlinks hook.

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 ensures that the internal CDI representation includes

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.

Since the `createContainer` `runc` hook runs with the environment that
the container's config.json specifies, the path to `ldconfig` may not be
easily resolvable if the host environment differs enough from the
container (e.g. on a NixOS host where all binaries are under hashed
paths in /nix/store with an Ubuntu container whose PATH contains
FHS-style paths such as /bin and /usr/bin). This change allows for
specifying exactly where ldconfig comes from.

This change adds support for an NVIDIA_NVSWITCH environment variable.
When set to `enabled` this striggers the injection of all available
/dev/nvidia-nvswitch* device nodes.

This change adds a driver root abstraction that defines how
libraries are located relative to the root. This allows for
this driver root to be constructed once and passed to discovery
code.

This change renames NewGraphicsDiscoverer to NewDRMNodesDiscoverer and
instead calls NewGraphicsMountsDiscoverer explicitly when constructing
a graphics modifier.
This avoids the import of config.Config into the discover package
which leads to a transitive dependency on toml-specifics and
requires that the vendor/github.com/pelletier/ package
be vendored in to consumers.

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.

This change switches to generating a OCI runtime hook to create
individual symlinks instead of processing a CSV file in the hook.
This allows for better reuse of the logic generating CDI
specifications, for example.

These changes remove the use of discover.Config which was used
to pass the driver root and the nvidiaCTK path in some cases.
Instead, the nvidiaCTKPath is resolved at the begining of runtime
invocation to ensure that this is valid at all points where it is
used.
