The TZoneAllocationFallback was added as an option in case we need to turn off TZoneHeap in only the WebContent process in order to avoid a memory regression. It turns out that we can enable TZoneHeap for all WebKit processes without regressing memory usage. So, this option is no longer needed, and can be removed to simplify the code.
