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.

This chagne allows the csv mode option to specified in the
nvidia-ctk cdi generate command and adds a --csv.file option
that can be repeated to specify the CSV files to be processed.

This change ensures that libcuda.so can be located on systems
where no patch version is specified in the driver version.

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.

This chagne prefers (non-symlink) sockets at /run over /var/run for
nvidia-persistenced and nvidia-fabricmanager sockets.

This change ensures that the update-ldcache hook is created in a manner
consistent with other nvidia-ctk hooks ensuring that a full path is
used.
Without this change the update-ldcache hook on Tegra-based sytems had an
invalid path.

If this is not done, the default config which sets the nvidia-ctk.path
option as "nvidia-ctk" will result in an invalid OCI spec if a hook is
injected. This change ensures that the path used is always an absolute
path as required by the hook spec.

This change adds an --nvidia-ctk-path to the nvidia-ctk cdi generate
command. This ensures that the executable path for the generated
hooks can be specified consistently.
Since the NVIDIA Container Runtime already allows for the executable
path to be specified in the config the utility code to update the
LDCache and create other nvidia-ctk hooks are also updated.
