Simulates an update for a collection of spaces in parallel, with the given time step.

Due to the implementation of physics spaces, a space can only be stepped a whole interval at once - you cannot start a step, then wait for it to finish later (this would allow starting multiple steps for different spaces at once, then waiting for all of them at the same time). However, through a specialized native function, we can achieve the same effect if we provide all the spaces that we want to step upfront.

Stages

The update step of a physics engine is typically split into:

• Broad-phase - collision pairs are generated between all Colliders, using a bounding volume hierarchy to accelerate these queries. These pairs are coarse, and do not guarantee that two bodies did actually collide.

• Narrow-phase - all collision pairs previously generated are checked to see if they actually collided, and if so, compute the contacts and forces necessary in order to resolve them.
