* Make box's mins and maxs static const.
* Use SSE to pack 4 indices into 1 128bit register, and shuffle to prevent duplication. Only 2 indices are used at the moment.
* Construct min/max for AI Script Network boxes using SIMD (significantly reduced instruction count!).
* Move NavMesh debug draw to dedicated class for future changes.
* Move AIN/NavMesh debug draw to ai_utility_shared.cpp.
* Use shift index + range for AIN debug draw.
* Added cvar for determining max distance between camera and tile (anything outside this range doesn't get draw).
