CheckBox Node doesn't support horizontal text position/text direction. It's always on the right side.

Godot's CheckBox Node also shows text on the right side of the screen.
My project needs text on top of the checkbox.

I know we can make a simple scene with CheckBox+Label but we waste the built-in text that a checkbox has. This is what I plan to do for now but using CheckBox directly would have been simpler and easier to manage.

We can go either of 2 ways to improve the CheckBox Node:

1. Implement a 'text direction w.r.t. the box' property for CheckBox Node.
2. Add and expose a check_h_offset property. Check already has and exposes theme_override_constants/check_v_offset for vertical offset which works great. This way we can use both offsets to make it appear on top of checkbox.
