### Issue description

If a `CharacterBody3D`'s parent node is in a position other than the origin, the difference will be included in its `get_position_delta()` value, and therefore also `get_real_velocity()`. This is because [the implementation](https://github.com/godotengine/godot/blob/3710f069293f2fde8afe33fea898c4b36fa5e943/scene/3d/physics_body_3d.cpp#L1782-L1784) subtracts the current **local** transform from the old **global** transform. I don't know if behaviour in this case is defined at all, but I would expect it to be consistent with everything else in the `CharacterBody3D` context, such that if `velocity` is zero, `get_position_delta()` is also zero. The same applies to `CharacterBody2D`.

### Steps to reproduce

1. Create a `Node3D` with a `CharacterBody3D` in it
2. Move the `Node3D`
3. Call `move_and_slide()` in the `CharacterBody3D` and observe `get_position_delta()`
