This has gotten sufficiently large enough to warrant moving it to its own source files. Especially given it dumps the file_sys headers around code that doesn't use it for the most part. This'll also make it easier to introduce a type alias for the compatibility list, so a large unordered_map type declaration doesn't need to be specified all the time (we don't want to propagate the game_list_p.h include via the main game_list.h header).
