[Static Runtime] Report static op statistics from graph when input size is zero (#73032)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/73032
Currently, ptvsc2_predictor_bench reports nothing when the input size is zero. However, Static Runtime's module creation has some useful information even after loading a model.
This change reports static op statistics when the given input's size is zero. In addition to that, this enables it to report the out variant coverage percentage, which is crucial to establish the baseline performance of Static Runtime.
Test Plan: - Ran `ptvsc2_predictor_bench` with this change as seen above.
