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 renames the csv.library-search-path option to
library-search-path so as to be more generally applicable in
future. Note that the option is still only applied in csv mode.

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.

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.

This change allows nvcdi.New to return an error in addition to the
constructed library instead of panicing.

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.

This change generates device folder permission hooks per device instead of
at a spec level. This ensures that the hook is not injected for a device that
does not have any nested device nodes.

These changes add a wsl discovery mode to the nvidia-ctk cdi generate command.
If wsl mode is enabled, the driver store for the available devices is used as
the source for discovered entities.

This change adds --discovery-mode flag to the nvidia-ctk cdi generate
command and plumbs this through to the CDI API.

This change adds an nvcdi package that exposes a basic API for
CDI spec generation. This is used from the nvidia-ctk cdi generate
command and can be consumed by DRA implementations and the device plugin.

This makes the intent of the command line argument clearer since this
relates specifically to the root where the NVIDIA driver is installed.

This change uses the `index` mode for the --device-name-strategy when
generating CDI specifications by default. This generates device names
such as nvidia.com/gpu=0 or nvidia.com/gpu=1:0 by default.
Note that this requires a CDI spec version of 0.5.0 and for consumers
(e.g. podman) that are only compatible with older versions one of the
other stragegies (`type-index` or `uuid`) should be used instead to
generate a v0.3.0 or v0.4.0 specification.

This change adds a --device-name-strategy flag for generating a CDI
specificaion. This allows a CDI spec to be generated with the following
names used for device:
* type-index: gpu0 and mig0:1
* index: 0 and 0:1
* uuid: GPU and MIG UUIDs
Note that the use of 'index' generates a v0.5.0 CDI specification since
this relaxes the restriction on the device names.

This change uses functionality from the CDI package to determine
the minimum required CDI spec version. This allows for a spec with
the widest compatibility to be specified.

This change adds an --nvidia-ctk-path to the nvidia-ctk cdi generate
command. This ensures that the executable path for the generated
hooks can be specified consistently.
Since the NVIDIA Container Runtime already allows for the executable
path to be specified in the config the utility code to update the
LDCache and create other nvidia-ctk hooks are also updated.
