This change adds a UsesNVGPUModule function that checks whether the nvgpu
kernel module is used by NVML. This allows for more robust detection of
Tegra-based platforms where libnvidia-ml.so is supported to enumerate the
iGPU.

This change introduced a config.Toml type that is used as the base for
config file processing and manipulation. This ensures that configs --
including commented values -- can be handled consistently.

This change ensures that the Config structs from internal.Config
are used for the NVIDIA Container Runtime Hook config too.

In order to properly handle systems with both iGPU and dGPU
drivers included, we skip "sym" mount specifications which
refer to .so or .so.[1-9] files.

This change explicitly generates a CDI specification from
the supplied CSV files when cdi mode is detected. This
ensures consistency between the behaviour on Tegra-based
systems.

Since the incoming OCI spec has already been parsed and used to
construct a CUDA image representation, pass this to the CSV
modifier constructor instead of re-creating an image representation.

This change sets the default CDI spec dirs at a config level instead
of when a CDI runtime modifier is constructed. This makes this setting
consistent with other options such as the nvidia-ctk path.

This change ensures that the nvidia-ctk config default command
generates a config file that is compatible with the official documentation
to, for example, disable cgroups in the NVIDIA Container CLI.
This requires that whitespace around comments is stripped before outputing the
contets.
This also adds an option to load a config and modify it in-place instead. This can
be triggered as a post-install step, for example.

This changes splits the functionality in the internal system package
into two packages: one for dealing with devices and one for dealing
with kernel modules. This removes ambiguity around the meaning of
driver / device roots in each case.
In each case, a root can be specified where device nodes are created
or kernel modules loaded.

These changes add a --load-kernel-modules option to the
nvidia-ctk system commands. If specified the NVIDIA kernel modules
(nvidia, nvidia-uvm, and nvidia-modeset) are loaded before any
operations on device nodes are performed.

This change adds an nvidia-container-runtime-hook.path config option
to allow the path used for the prestart hook to be overridden. This
is useful in cases where multiple NVIDIA Container Toolkit installations
are present.

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 change adds a symlinks.Resolve function for resolving symlinks and
updates usages across the code to make use of it.
