Physics rewrite + collision system

[RoseThornrime]

• update the physics system to match other systems: change components' names, reuse transform component for position, remove nesting in components
• add an interactive example
• add angular movement
• make collider points' positions relative to the transform
• implement OBB collider
• implement the SAT algorithm (much faster than GJK for simple 2D shapes)
• implement: circle collider, triangle collider, vertical and horizontal line colliders
• rewrite collision actions to events like in the input system

how to add angular movement:

• write a helper function to get quaternion from angle
• rotate a point around the center
• add angular velocity and use it for angular movement

It's possible that glm has such functions implemented

[RoseThornrime]

The best thing I've found is sth like:

inline Quat quaternion(f32 angle) {
	return glm::angleAxis(glm::radians(angle), float3(0.0f, 0.0f, 1.0f));
}

and I've added it to Math.h

It's also more convenient because we're writing a 2D engine, so you can avoid using quaternions directly in examples

		auto& transform = e.addComponent<scene::components::TransformComponent>({
			listenerPosition,
			quaternion(0.0f),
			{ 100.0f, 50.0f, 0.0f },
		});
