Optimize WMO rendering and collision performance

Browse source 
- Add texture-sorted batch merging with glMultiDrawElements to reduce draw calls
- Pre-compute merged batches at load time instead of per-frame
- Add persistent floor height cache with disk save/load (cache/wmo_floor_cache.bin)
- Reduce collision focus radius and sweep steps for faster collision checks
- Add floor cache size to performance HUD
- Reduce WMO group distance culling to 80 units
