Add support for any reflect structure, even one that contains asset handles, as long as those handles reference a file with a known path.

[rewin123]

Add a new method for registering components

app.editor_auto_struct()

which registers a component, allows to visualize it in the inspector, but saves not T, but AutoStruct, which contains the same T fields as DynamicStruct, but converts all handle fields to the path to the asset file. And when loading prefab AutoStruct should be converted to T by inserting one field at a time. And load all assemblies by saved paths from AutoStruct

This will allow to add support for such components as StandartMaterial.
