b4dc1f338d Generate nested device folder permission hooks per device
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.

b21dc929ef Add WSL2 discovery and spec generation
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.

5b110fba2d Add nvcdi package with basic CDI generation 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.

cfa2647260 Rename root to driverRoot for CDI generation
This makes the intent of the command line argument clearer since this

f768bb5783 Use device index as CDI device names by default
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.

89bf81a9db Add --device-name-strategy flag for CDI spec generation
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.

35df24d63a Make handling of nvidia-ctk path consistent
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.
