Summary JSNativeStdFunction should be able to safely capture

Currently, there's no way to safely keep the captures of lambdas passed to JSNativeStdFunction::create alive other than use of Strong, which has its own problems. If JSNativeStdFunction kept a FixedVector of WriteBarriers to captured values, it could keep them alive at least as long as the JSNativeStdFunction is alive without Strong cycle issues.
