Added a create rectangle button to the tileset editor.

It makes easier to create collision/occlusion/navigation shapes covering the full tile.

It still creates a ConvexPolygonShape2D under the hood.

IMO, The UX is still pretty bad but it's better than before where you had to click each tile's four corners to create a shape.

Is there a specific reason for not using RectangleShape2D in this case?

AFAIK occlusion and navigation can only use polygons and I didn't want to deal with the specific part of the code that deals with creating the shapes 😅

Thanks!
