nvsandboxutils: Add internal bindings

This change adds the internal bindings for Sandboxutils, some of which
have been automatically generated with the help of c-for-go. The format
followed is similar to what is used in go-nvml. These would need to be
regenerated when the header file is modified and new APIs are added.
