Migrate user data folder for MacOSX

[Alexandre H.T.R. Bonfitto]

Today, for Mac OSX, PororocaUserData folder is right next to the application, in Applications folder.

But for Mac OSX, the conventional folder location of app data is:

For preferences: /Users/username/Library/Preferences
For user data: /Users/username/Library/Application Support

We can use Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData) in this case too.

https://github.com/dotnet/runtime/blob/092cbed116fe0c661d40bf8657fbe759020b0cab/src/libraries/System.Private.CoreLib/src/System/Environment.GetFolderPathCore.Unix.cs#L97

Migration needs to move and merge former PororocaUserData folder, from next to application to the Application Support folder.
