This change adds a cache to the mounts type. This means that if called to get
a list of folders, for example, the result is reused instead of recalculated.
This also avoids duplicate logging.

This change adds a discovered hook for updating the ldcache as a container-create
hook. The mounts from a discoverer are inspected to determine the folders that must
be added to the cache using the nvidia-ctk hook update-ldcache command.
This is added to the "csv" discovery mode for the experimental runtime.

This change adds an 'auto' discover mode that attempts to select the correct mode
for a given platform. This currently attempts to detect whether the platform is a
Tegra-based system in which case the 'csv' discover mode is used. The 'legacy'
discover mode is used as the fallback.

This change ensures that by default, the CSV discovery only considers the base CSV
files (l4t.csv, drivers.csv, devices.csv) and skips the rest unless the
NVIDIA_REQUIRE_JETPACK is set to "csv-mounts=all", in which case, all CSV files in the
specified folder are considered.

This change adds support for a "csv" discovery mode to the experimental runtime.
If this is set with experimental = true, a CSV-based discovery of devices and
mounts are used to define the modifications required to the OCI spec. The edits
are expressed as CDI ContainerEdits.

This change adds a symlink locator that follows symlinks and returns all
elements in the chain and a device locator that finds character devices.

This change enables the experimental mode of the NVIDIA Container Runtime. If
enabled, the nvidia-container-runtime.discover-mode config option is
queried to determine how required OCI spec modifications should be defined.
If "legacy" is selected, the existing NVIDIA Container Runtime hooks is
discovered and injected into the OCI spec.

This change imports the modifying runtime abstraction from the
experimental branch. This encapsulates the checks for whether
modification is required, and forwards the loaded spec to
the specified modifier. This allows for the same code to be
reused when performing more complex modifications.
