PR Overview
This PR addresses the issue of detecting the [DisableRuntimeMarshalling] attribute when it is referenced from assemblies other than System.Runtime.dll. The changes refactor inline string comparisons into a new helper method and apply it in both type definition and member reference contexts.
- Introduced the IsDisableRuntimeMarshallingAttribute helper method.
- Replaced inline attribute checks with the new helper method for clearer logic.
- Updated attribute checks for both direct and member reference cases.

- Ensure unit tests cover scenarios for both direct type definition and member reference attribute detections using IsDisableRuntimeMarshallingAttribute to confirm the fix works under all expected conditions.
