Clean up thread pool usage (#11681) 
Using an unbound LinkedBlockingQueue means you *have* to set core and max core thread pool size the same, as they will never go above the minimum pool size by just passing them through. So this fixes the async command executor pool to actually use 2 threads, and also cleans up other usage to be explicitly "fixed" thread pool sizes, and splits off one more in Minecraft's Util class
