Reorder mode drops special class annotations: tool and icon

These annotations get deleted when using reorder mode:

```gdscript
@tool
@icon("res://icon.svg")
class_name TestClass
extends Node
```

Generally the code reorder now captures all nodes but does not use them all in the output. It should just make sure it at least drops no nodes/uses all nodes. if there are no rules for where to place a node, just add it to the output as it's looped over
