add flag for dynamic shapes to filter out static ops (#3733)

Summary:
Pull Request resolved: https://github.com/pytorch/executorch/pull/3733

Since we have updated XNNPACK to support almost 100% of dynamic shape ops, we can now create static_op lists which do not have any dynamic shape support and filter them out instead
