This change updates the way we construct a discoverer for tegra systems to be more flexible in terms of how the SOURCES of the mount specs can be specified. This allows for subsequent changes like adding (or removing) mount specs at the point of construction. Signed-off-by: Evan Lezar <[email protected]>

This change allows CDI specs to be generated for multiple devices when using CSV mode. This can be used in cases where a Tegra-based system consists of an iGPU and dGPU. This behavior can be opted out of using the disable-multiple-csv-devices feature flag. This can be specified by adding the --feaure-flags=disable-multiple-csv-devices command line option to the nvidia-ctk cdi generate command or to the automatic CDI spec generation by adding NVIDIA_CTK_CDI_GENERATE_FEATURE_FLAGS=disable-multiple-csv-devices to the /etc/nvidia-container-toolkit/nvidia-cdi-refresh.env file.
