Checks whether the Cache Server is configured to enable import result caching. Import result caching is disabled by default for new projects in Unity 6.5. Import result caching can be enabled by passing the command line argument -cacheServerEnableImportResultCaching or setting the environment variable UNITY_CACHE_SERVER_IMPORT_RESULT_CACHING_ENABLED. Projects created prior to Unity 6.5, that are upgraded to Unity 6.5, that have import result caching enabled in Editor Settings or Editor Preferences, will continue to have import result caching enabled.
