[easy] ThroughputBenchmark: make ScriptModuleBenchmark usable from c++ (#35848)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/35848
This class so far was used from Python binding only. As a result, testing in c++ only environment is not currently possible. More specifically, adding inputs requires using
py::args and py::kwargs. This PR fixes this by adding another addInput function to ScriptModuleBenchmark class.
Test Plan: Imported from OSS
