provide Dictionary<T, V> to native implemented, because we found the iterator so slower than python

as these issues show:
#43720
#42426

the dictionary iterator so slower, I think it is better to provider native implemented of List and Dictionary, like Array.

The fact that the interpreter is currently slow on these method is not enough of a reason to change the whole bcl implementation. Will keep an eye on tests from #42426, for future interp optimizations

ok, thank you.
but you can provide the native dicionary like py_dict other than replace dictionary.
