Change default profile-dir

Change default profile-dir to be:
 - %localappdata%\Telerik\.nativescript-cli for Windows
 - ~/.local/share/Telerik/.nativescript-cli for MacOS and Linux

Update common lib where the following change is applied: DefaultValue is passed to the setProfileDir method. Different CLI-s have different defaultProfileDirs. setProfileDir method will use the passed on the command line profile-dir or the default one passed as parameter to the function.
