Reviewed by Darin.

Initialize functionQueueMutex in a safe manner.

• wtf/MainThread.cpp: (WTF::functionQueueMutex): Made it an AtomicallyInitializedStatic.

(WTF::dispatchFunctionsFromMainThread):
(WTF::setMainThreadCallbacksPaused):
Assert that the current thread is main, meaning that the callbacksPaused static can be
accessed.
