Changed all checks for !gPlayState to !GameInteractor::IsSaveLoaded() in mods.cpp for all the cheats, and added the same full check to others that really didn't need to be running outside of a game (like infinite rupees, magic, health, etc), and clear any triggering CVars. (#3441)

Changed `RegisterSwitchAge()` to clear the CVar instead of setting it to 0.
