Although the nvidia-ctk cdi generate command generates
specs with 644 permissions, the nvidia-ctk cdi transform
commands do not. This change sets the default permissions
to 600 instead of 644.

This changes adds an option to the toolkit container to allow
the dev root to be specified. This adds support for driver installations
where the driver files are at one root and the dev nodes are created
elsewhere -- most typically at /. This is the case, for example, for
GKE driver installations.

This change ensures that nvnllib and devicelib are constructed
before these are used to construct infolib.

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.

This change moves from using strings to useing device.Identifiers
as input for requesting CDI specifications for specific
devices.

This change ensures taht NVIDIA_VISIBLE_DEVICES=void is included in
generated CDI specs. This prevents the NVIDIA Container Runtime Hook
from injecting devices if NVIDIA_VISIBLE_DEVICES=all is set.

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 renames the root transformer to indicate that it
operates on host paths and adds a container root transformer for
explicitly transforming container roots.
The transform.NewRootTransformer constructor still exists, but has
been marked as deprecated.

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.

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 refactors the use of the symlink filter to make it extendible.
A blocked filter can be set on the Tegra CSV discoverer to ensure that the correct
symlink libraries are filtered out. Here, globs can be used to select mulitple libraries,
and a **/ prefix on the globs indicates that the pattern that follows is only applied to
the filename of the symlink entry in the CSV file.
A --csv.ignore-pattern command line argument is added to the nvidia-ctk cdi generate
command that allows this to be set.

with a --config-mode=oci-hook that creates an OCI hook json file.
