### Issue description

The description of `Control._has_point(position)`-virtual function is outdated likely due to #66688. 

> Note: If you want to check if a point is inside the control, you can use `get_rect().has_point(point)`.

After #66688, get_rect() returns the Controls rect relative to its parent, while the point is relative to the Control.

Also, the note refers to `point` while it likely should refer to the parameter `position`. That said, in this case, I think the incorrect name is better and the parameter of the function should be changed to`point` to avoid shadowing `Control.position`.

Suggested fixes:
1. Change the note to match the new behavior (`Rect2(Vector2.ZERO, size).has_point(point)` should work; verify) OR introduce `get_local_rect()` that matches the old behavior and recommend using it instead.
2. Change the name of the `position` parameter to `point` in `Control._has_point(position)`
