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 extends the nvidia-ctk runtime configure command
with a --config-mode=oci-hook that creates an OCI hook json file.

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.

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.

The nvcid api is extended to allow for merged device options to
be specified. If any options are specified, then a merged device
is generated.

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.

Since we relied on finding libcuda.so in the LDCache to determine both the CUDA
version and the expected directory for the driver libraries, the generation of the
management CDI specifications fails in containers where the LDCache has not been updated.
This change falls back to searching a set of predefined paths instead when the lookup of
libcuda.so in the cache fails.

CDI generation modes such as management and wsl don't require
NVML. This change removes the top-level instantiation of nvmllib
and replaces it with an instanitation in the nvml CDI spec generation
code.

These changes add support for generating a management spec to the nvcdi API.
A management spec consists of a single CDI device (`all`) which includes all expected
NVIDIA device nodes, driver libraries, binaries, and IPC sockets.
