Bug 1604549 - remove scriptability and classinfo from nsThreadPool; r=bzbarsky

There's no reason for this class to be exposed to script; it'd be
awkward to use from script anyway, because the runnables script
dispatches would be running off the main thread.  Thread pool listeners
likewise can't be exposed to script or implemented by script, because
they are also running off the main thread.  The classinfo stuff just
seems like a relic from a bygone era.
