This change adds a new discoverer for Sandboxutils to report the file system paths and associated symbolic links using GetGpuResource and GetFileContent APIs. Both GPU and MIG devices are supported. If the Sandboxutils discoverer fails, the NVML discoverer is used to report the file system information.
