[Operator Versioning] Remove version compare as they are decoupled now (#71461)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/71461
After operator versioning work, the version in model file is used for operator versioning, while bytecode_version is used for bytecode versioning (for bytecode schema). They are two seperate things now and this comparison is not needed.
