I'm planning to add localization support for these analyzers.

These are the roadmap I'm planning to do:

- [ ] Add a LocalizableResources project. This project contains the main Resources.resx file and several localized files such as Resources.zh-CN.resx.
- [ ] Move all diagnostic strings which are currently not been deprecated to the localized Resources.resx files.
- [ ] Change the `CodeGeneration.DiagnosticDescriptorsGenerator` file and replace the literal strings to localizable strings which all reference the LocalizableResources project.

I'm just planning to do this but find that this is not a tiny task. So I'm here to discuss this with you for your approval. If you agree to do this, I'll start to add the localization support for this repository. I'll add `en-US` and `zh-CN` for the first version and hope the community to add others.
