savedata_factory: Automatically create certain savedata

Browse Source 
After further hardware investigation, it appears that some games, perhaps those more lazily coded, will not call EnsureSaveData, meaning that they expect the normal (current) save to be automatically made. Additionally, some games do not create a cache or temporary save before use.
In these 3 specific instances, the save is created automatically for the game if it doesn't exist.
