Added the `HierarchyEditor` and `LocalToWorldEditor` classes to implement custom component editing functionality. Added the `Vector3Field` control for 3D vector manipulation and its corresponding XAML definition. Added the `ComponentDataView` and `ComponentObject` classes to manage component data display and access. Added the `CustomEditorAttribute` to mark classes as custom editors for specific components. Changed the `IInspectable` interface to use properties for `Icon`, `HeaderContent`, and `InspectorContent`. Changed the `PropertyField` class to enhance UI control binding capabilities. Changed the `EditorWorldManager` to improve world data loading and deserialization processes. Changed the `EntityNode` and `WorldNode` classes to update entity construction and component querying. Changed the `StaticResource` class to include new binding flags for component properties. Changed the `InspectorService` to remove old contract references and adopt new interfaces. Changed the `QueryEnumerable` and related files to update generic constraints for improved type safety. Changed the `QueryItem` class to reflect new generic constraints and enhance deconstruction. Changed the `World.Query` methods to utilize the updated generic constraints. Updated the `SerializationTest` to align with new entity creation and management practices.
