* FastPoly
* Inline polygon vertices
No more pooling, pooling bad. No more arrays in engine, only span.
I made a slim version that's only the 4 verts so no padding on it compared to Polygon. Slightly more clamplicated code but entitylookup + mapmanager are both hotpaths and it's easy to do. Memory usage will likely go up for now but heap allocations should drop significantly due to removing the pooling.

Added a poly struct with the intention of replacing the existing one whenever I finish box2c port.
