Reduce CPU load when moving around the world

Should've made this multiple commits, but too late now

- Create ConfigThreadPool to remove duplicate thread setup/config code
- Move configurable thread pools into their own ThreadPools class
- Add a semaphore to limit how many LOD builder/lighting/bufferBuilder threads can be active at once
