[no-relnote] Get low-level runtimes consistently
We ensure that we use the same low-level runtimes regardless
of the runtime engine being configured. This ensures consistent
behaviour.

This change aligns the creation of symlinks under CDI with
the implementation in libnvidia-container. If the driver libraries
are present, the following symlinks are created:
* {{ .LibRoot }}/libcuda.so -> libcuda.so.1
* {{ .LibRoot }}/libnvidia-opticalflow.so -> libnvidia-opticalflow.so.1
* {{ .LibRoot }}/libGLX_indirect.so.0 -> libGLX_nvidia.so.{{ .Version }}

This change refactors the toml config file handlig for runtimes
such as containerd or crio. A toml.Loader is introduced that
encapsulates loading the required file.
This can be extended to allow other mechanisms for loading
loading the current config.

This change adds the vdpau subfolder to the paths searched
for driver libraries. This allows the libvdpau_nvidia.so.RM_VERSION
library to also be discovered.

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 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
the persistenced socket if the include-persistenced-socket feature
flag is enabled.

This change updates the logic to populate the options for the
nvidia runtime configs added to containerd or crio from a default runtime
if this is specified and a runc entry is not found.
This allows the default runtime values for settings such as SystemdCgroup
to be applied correctly.

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.

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.
