Allow the JS objects to have more than one native pointer data (#2814)

Browse Source 
Currently JS objects can only have one native pointer data which could be a limitation in special cases.
This patch allows to register multiple native infos, which can be accessed/associated with the corresponding `jerry_object_native_info_t`.
