* 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
