Filter tensor arguments from traced model. (#5689)
* Filter tensor arguments from traced model.
This PR filters tensor arguments from the list of arguments that would be given to the
model.
**Problem:** dynamo bridge assumed all arguments were tensors.
**Solution:** filter tensor arguments so that we correctly collect tensor information.
* Add test.
* Fix lint issues.
* Simplified test.
* Use `openxla` instead of `openxla_eval` backend.
* Rename variables for readability.
* Use `openxla_eval` instead of `openxla`.
