Provide WASM support for Physics

Ideally keep the current system as fallback, and provide WASM integration where available. There's a number of existing libraries for this like Rapier, Ammo.js, etc. This might be easier if the Physics was some kind of modular plugin.

actually I was thinking that an easy one to start with this thing is to provide a WASM based implementation for vector and matrix classes, this should (?) be a low hanging fruit and will benefit the physic implementation right away !
