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.

This change refactors the generation of CDI specifications
to use discoverers and generate the CDI specifications from these
discoverers. This allows for better reuse.

This change replaces the `--json` flag of the nvidia-ctk cdi generate
command with a --format flag that accepts a string format of either
json or yaml.
