Also slightly update the cases for canSaveGameStateCurrently()
The game has its own autosave mechanism (at the start of each new Act). Also currently the label for the ScummVM autosave can be in the wrong language (since it is in the ScummVM's GUI language, but not necessarily in the game's own GUI language) and in KIA it could appear illegible as "?????? ??????" for non Latin languages.
The autosave refactoring that was done in
7adad5aaf5 used g_engine for identifying the
autosave slot. This worked for in-game save/load, but doesn't fit when
called from the launcher.
Fix by passing MetaEngine to SaveStateDescriptor ctor and using it for this
query.
Amends 7adad5aaf5.
For each engine:
- Make a new folder detection
- Move detection-related files inside the folder
- Add a new module "enginename/detection"
- Add DETECT_OBJS here
- Adjust the normal engine module to remove detect_objs
- Adjust every file for the new changes.
