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 improves the testibility of the CSV discoverer.
This is done by adding injection points for mocks for library discovery and
symlink resolution.
Note that this highlights a bug in the current implementation where the
library filter causes valid symlinks to be skipped.

This change adds a "required" option to the new toml config
that controls whether a default config is returned or not.
This is useful from the NVIDIA Container Runtime Hook, where
/run/driver/nvidia/etc/nvidia-container-runtime/config.toml
is checked before the standard path.
This fixes a bug where the default config was always applied
when this config was not used.

This change adds a UsesNVGPUModule function that checks whether the nvgpu
kernel module is used by NVML. This allows for more robust detection of
Tegra-based platforms where libnvidia-ml.so is supported to enumerate the
iGPU.

This change updates go-nvlib to include logic to skip NVIDIA PCI-E
devices where the name or class id is not known.

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 simplifies the nvidia-ctk config default command.
By default it now outputs the default config to STDOUT, and can
optionally output this to file.

This change introduced a config.Toml type that is used as the base for
config file processing and manipulation. This ensures that configs --
including commented values -- can be handled consistently.
