refactor(runtime): remove incomplete GetRuntimeStatus function implementation (#5792)

- Deleted the unfinished GetRuntimeStatus function which retrieved runtime status by type, name, and namespace
- Cleaned up unused code and comments related to runtime status retrieval
- Retained and organized existing RuntimeInfo interface and related helper functions for runtime info construction
- Ensured the code only includes fully implemented and functional parts to improve maintainability
