Add onnxifi interface for set/get options (#52388)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/52388
Pull Request resolved: https://github.com/pytorch/glow/pull/5364
This allows us to change global variables through onnxifi calls. And add python bindings along with it. Note that we supply a dummy backend_id as it's not needed by glow due to setting being global.
