GameSettings: Approve speed hacks for RetroAchievements

Some of the speed hacks were not approved for RetroAchievements, meaning that users had to choose between not getting hardcore achievements, or having poor performance.

Also, renamed the instances of `$Limit internal FPS to VPS (improves performance)` to `$Limit internal frame rate (speed hack)` for consistency. They are enabled by default, so unless the user disabled them, it won't break the configuration.
