1. Remove the "init", "reset", "getRoot" and "receiveTasks" APIs, which
are already implemented in the new version of "weex-js-runtime".
2. Use "createInstanceContext" instead of "createInstance". Vue only
needs to prepare the instance context and no longer execute the js
code. The js code will be executed by native.
3. Add flow type declarations and annotations.
