Restructure code object source code (#826)

* public codeobj info

* Restructure code object source code file layout

* Update get_unloaded_code_objects + add iterate_loaded_code_objects

* Remove get_unloaded_code_objects from visible internal API

- iterate_loaded_code_objects + functor which filters on the hsa_executable_t effectively reproduces this behavior

* Whitespace removal
