Fix custom collision shape drawing in physics tests:
CollisionShape debug draw has changed in 3.3 and now requires a body
to be rendered, so the trick to display custom physics shapes in the
physics tests had to be updated.
Cylinder support:
Now cylinders are supported in Godot Physics, so the exception to avoid
spamming errors when cylinders are used can be removed.
Rigid body picking:
Added mouse-picking to Test Shapes in both 2D and 3D.
Add Functional Test / Stack & Pyramid
For testing stack stability.
Add Functional Test / Raycasts
Visually test raycast on different shapes.
Add Performance Test / Broadphase
Add/move/remove lots of non-colliding objects and measure time.
Fix leaks on exit
Some Nodes are copied and removed from the scene to be used as templates,
they need to be freed manually on exit.
Fix Performance Test / Contacts
Positions adjusted, some shape types were not created at the center.
