Update broadphase performance test in physics tests

Start logging physics tick one frame earlier for each operation
Disable debug collision to avoid rendering bottleneck
Fixes in adding/removing bodies to avoid bottlenecks outside of physics
2D: Increase message queue size to allow adding more objects at once
3D: Remove camera to disable rendering altogether
3D: Fix error with create_rigidbody_box missing default value
