Configure shadow-rs to run only once during development

[leaf-potato]

After using shadow-rs, even if no code is modified, the code generated by shadow-rs will cause the code that depends on shadow-rs to be recompiled, which is very bad in large projects. If shadow-rs can be configured to run only once during local development, the user experience will be better.

Thank you for the feedback. It should need to solve it.
