Add TorusShape3D for collisions

[venilark]

There is TorusMesh, CSGTorus but no TorusShape3D, how is it?
I tried to implement a ring that gets bigger over time while keeping the same thickness but that meant changing the collision shape and I couldn't do it, or didn't know how, so I had to rely on the CSGTorus and check the collision with it with another Area3D, a really bad solution that wouldn't be necessary with this new collision shape.
