bool 该对象是预制件的一部分，则返回 true。

For Prefab contents loaded in Prefab Mode, this method will not check the Prefab Asset the loaded contents are loaded from, since these Prefab contents are loaded into a preview scene and are not part of an Asset while being edited in Prefab Mode. This means that for Prefab contents in Prefab Mode, the method will return true for Prefab instances, but not for GameObjects or components that are not part of a Prefab instance. To check if an object is part of Prefab contents in Prefab Mode, use PrefabStage.IsPartOfPrefabContents.
