Lioncash bd8065295c yuzu: Move compatibility list specifics to their own source files
Lets us keep the generic portions of the compatibility list code
together, and allows us to introduce a type alias that makes it so we
don't need to type out a very long type declaration anymore, making the
immediate readability of some code better.
