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.

This change generates CDI specifications for Tegra devices
with the nvidia.com/gpu=0 name by default. The type-index
nameing strategy is also supported and will generate a device
with the name nvidia.com/gpu=gpu0.
The uuid naming strategy will raise an error if selected.

Path to locate the GSP firmware is explicitly set to /lib/firmware/nvidia.
Users may chose to install the GSP firmware in alternate locations where
the kernel would look for firmware on the root filesystem.
Add locate functionality which looks for the GSP firmware files in the
same location as the kernel would
(https://docs.kernel.org/driver-api/firmware/fw_search_path.html).
The paths searched in order are:
- path described in /sys/module/firmware_class/parameters/path
- /lib/firmware/updates/UTS_RELEASE/
- /lib/firmware/updates/
- /lib/firmware/UTS_RELEASE/
- /lib/firmware/

This change uses the actual discovered path of nvidia-smi when
creating a symlink to the binary on WSL2 platforms.
This ensures that cases where multiple driver store paths are
detected are supported.

The nvcid api is extended to allow for merged device options to

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.

As simplified CDI spec has no duplicate entities in any single set of container edits.
Furthermore, contianer edits defined at a spec-level are not included in the container
edits for a device.
