如果给定对象是预制件资源的一部分，则返回 true。
This method returns true if the component or GameObject is part of a Prefab Asset.
It returns false if the object is part of a Prefab instance in a scene. To check if an object is part of a Prefab instance, use PrefabUtility.IsPartOfPrefabInstance or PrefabUtility.IsPartOfNonAssetPrefabInstance.
It also returns false for Prefab contents loaded in Prefab Mode, since these Prefab contents are loaded into a preview scene and are not part of an Asset while being edited in Prefab Mode. To check if an object is part of Prefab contents in Prefab Mode, use PrefabStage.IsPartOfPrefabContents.
