Add native functions to module info

[garazdawi]

Is your feature request related to a problem? Please describe.
We need a way to get information about which functions in a module is backed by native code, both nifs or bifs.

Describe the solution you'd like
the funcion lists:module_info(native_functions) should return a list of functions that are implemented using native code. It should return both exported and private functions.
