Sananya Majumder dcbf5bc81f nvsandboxutils: Add implementation for the APIs
This change adds manual wrappers around the generated bindings to make
them into more user-friendly APIs for the caller. Some helper functions
are also added.
The APIs that are currently present in the library and implemented here
are:
nvSandboxUtilsInit
nvSandboxUtilsShutdown
nvSandboxUtilsGetDriverVersion
nvSandboxUtilsGetGpuResource
nvSandboxUtilsGetFileContent
