revert(weex): remove the new Function hack for V8, as Weex uses JSC now

Remove the `callFunctionNative` method and `compileBundle`, which is provided by modified V8. In
order to maintain the consistency of the js engine, Weex also use JSC on Android. The legacy hack
for V8 engine should be removed.
