Inherit settings from region-free INIs to region-specific INIs

Having settings for each game in more than one file is redundant.
Now, region-free INIs are now only for settings, and region-specific
INIs are only for AR codes and patches. Exceptions are made for
titles that share the first three characters of their IDs with
unrelated titles (mostly unlicensed titles and Triforce titles).
