wraitii f73fa05542 Cache the model-animation bounds more efficiently.
To render models, we need to know the maximum bounds it takes over the
course of an animation. This depends only on the ModelDef and the
AnimationDef (and thus the SkeletonDef).
Currently, we recompute this data for each model, which is inefficient.
Caching it in ModelDef is faster, particularly avoiding lag spikes at
game start on some maps.
The animations are referred by a unique ID to avoid pointer-related
issues. I would have preferred weak_ptr, but that cannot be stably
hashed for now.

While at it, switch to unique_ptr/vectors.
