Title: closed #3463: Potential hash collision by using typeid(T).hash_code() in JSB and LuaBinding.

Instead of using std::unordered_map(long is the hash_code generated by typeid(T).hash_code()),
We needs to use std::unordered_map to avoid collision since unordered_map internally processes collisions.
