SCI32: Disable all SCI32 Mac code

This code is currently untestable and is almost certainly at least
partly based on guesswork & not actual reverse-engineering (as was
the case for all other pre-2015 SCI32 code), so future developers
interested in adding SCI32 Mac support should use it only as an
intermediate reference rather than as known good code.
