Sdk/[Collision|Physics]Component2D: Set internal rigidbody userdata to the entity id

ChangeLog.md

@@ -102,6 +102,7 @@ Nazara Development Kit:
 - ⚠️ Renamed World::Update() to World::Refresh() for more clarity and to differentiate it from World::Update(elapsedTime)
 - World entity ids are now reused from lowest to highest (they were previously reused in reverse order of death)
 - World now has an internal profiler, allowing to measure the refresh and system update time
+- CollisionComponent[2D|3D] and PhysicsComponent[2D|3D] now configures their internal RigidBody userdata to the entity ID they belong to (useful for callbacks)
