"Add [...] Component" nodes aren't exposed

[mihe]

These seem to be handled in blueprint through UK2Node_AddComponent.

The current workaround would be something similar to how it is in C++:

export function construct(target: BP_Foo, mesh: StaticMesh) {
    const component = new StaticMeshComponent(target);
    component.registerComponent();
    component.setStaticMesh(mesh);
    target.addOwnedComponent(component);
}
