I added `TCastleControl.DesignUrl` and `TCastleControl.DesignedComponent` to easier load designed UI in `TCastleControl`, and even see the designed UI in Lazarus form inspector.

The short documentation is [added to TCastleControl chapter](https://castle-engine.io/control_on_form).

Our engine examples [examples/lazarus/model\_3d\_with\_2d\_controls](https://github.com/castle-engine/castle-engine/tree/master/examples/lazarus/model_3d_with_2d_controls) and [examples/lazarus/two\_controls](https://github.com/castle-engine/castle-engine/tree/master/examples/lazarus/two_controls) use it already.
