Improve Thread Pool usage to allow single threads for single cpu servers
Switch to a standard fixed size ThreadPoolExecutor as we don't use the
advanced capabilities of a ForkJoinPool.

ForkJoinPool does not allow single threads, and really rather not use
2 different executor types based on core count.

Also, change thread priorities so that main thread is prioritized by
the OS at a higher priority than the other threads. May not help too much
but it at least signals the OS the information to know main is more important.

Subject: [PATCH] Fix CraftServer#isPrimaryThread and MinecraftServer
isMainThread
md_5 changed it so he could shut down the server asynchronously
from watchdog, although we have patches that prevent that type
of behavior for this exact reason.
md_5 also placed code in PlayerConnectionUtils that would have
solved https://bugs.mojang.com/browse/MC-142590, making the change
to MinecraftServer#isMainThread irrelevant.
By reverting his change to MinecraftServer#isMainThread packet
handling that should have been handled synchronously will be handled
synchronously when the server gets shut down.
