### Issue description

`GraphNode` class declares members with conflicting names.  
- `selected` property: https://github.com/godotengine/godot/blob/0daa86d70e7338506c37bee6b6e0c4aba7255d68/scene/gui/graph_node.cpp#L1154
- `selected` signal: https://github.com/godotengine/godot/blob/0daa86d70e7338506c37bee6b6e0c4aba7255d68/scene/gui/graph_node.cpp#L1164

As now signals are truely members of the class, this leads to name colliding in several languages.  
- In GDScript, the signal can't be used as it is treated as a property:

- In Kotlin, the generated API code cannot compile as signal and property declarations are conflicting:
```
e: ~\git\godot\modules\kotlin_jvm\kt\godot-library\src\main\kotlin\godot\gen\godot\GraphNode.kt: (53, 14): Conflicting declarations: public final val selected: Signal0, public final var selected: Boolean
e: ~\git\godot\modules\kotlin_jvm\kt\godot-library\src\main\kotlin\godot\gen\godot\GraphNode.kt: (182, 14): Conflicting declarations: public final val selected: Signal0, public final var selected: Boolean
```

### Steps to reproduce

Try to use `selected` signal from GDScript.
