SCI: SCI2/2.1 kernel table changes

- Mark several SCI2/2.1 kernel functions used for debugging as dummy
- Added an empty function for kSetWindowsOption, used for settings specific to
Windows versions (e.g. showing/hiding the title bar)
- Added a stub for kGetWindowsOption (currently returning 0 to a Windows related
option for Phantasmagoria)
