This fixes a build error when `-DENABLE_TESTS=ON` and `-DUSE_RETRO_ACHIEVEMENTS=OFF` are both set together, since AchievementManager is also behind an ifdef.
Refactors the PatchAllowlistTest to streamline the experience for developers. Instead of a textual description of what needs to change in ApprovedInis.json for RetroAchievements compatibility, the test will now generate a replacement file and instruct the coder where to copy it in their local branch, and what to update APPROVED_LIST_HASH to. The result should be easier and more instructive for developers to make changes, while still maintaining that allowed codes cannot be added or modified without recompiling Dolphin.
As ApprovedInis.json no longer needs to be user-readable for this process, it no longer contains titles or pretty formatting and as such is updated in this commit, hash included.
New code adds a test failure if there's a Patches/Gecko/AR_Retroachievements_Verified code that doesn't appear to actually exist in the file. This will catch if the allowed patch is formatted wrong, which I found happening several times already due to not realizing that the patch author's name would need to be omitted.
