refactor: move COM type and guard into independent file

Browse Source 
- move COM types and guard into independent file and namespace COMHelper because not only dialog, but also other parts also need to use COM related fucntion.
- remove ParserHelper.cpp because it is empty (ParserHelper is header only namespace).
- Add a function fetching LOCALAPPDATA in WinFctHelper.
