Added additional Rapier physics examples

[NikLever]

I've added 4 additional Rapier Physics examples

physics_rapier_basic.html - simple example of using rapier
physics_rapier_joints.html - example of using rapier joints
physics_rapier_character_controller.html - using a rapier character controller to use a collider under user control
physics_rapier_vehicle_controller.html - using rapier DynamicRaycasrVehicleController to create a car example

Adapted jsm/physics/RapierPhysics.js added more geometry to collider options and a debugger class that displays all colliders as outlines

I'm guessing the failed comparison of the screenshot physics_rapier_basic is because it uses a randomised colour for the dropping bodies. I've added an exception.

Do you mind updating the basic visuals of the demos so they match physics_ammo_break?

Specifically, use the background and floor setup from the ammo demo. That should make the scenes brighter and friendlier.

Please add the new examples to the tags.json file so they are marked as external:
