Give MotU trophy in normal mode

This makes it so that it is possible to obtain the Master of the
Universe trophy/achievement, usually unlocked by beating No Death Mode,
outside of NDM.

There are several conditions that need to be met:

1. The game needs to be started from a new game and cannot be from
   loading a save.
2. Accessibility modes (invincibility and slowdown) must never be
   enabled.

If either condition is violated, then the boolean that keeps track of
NDM eligibility will be set to false.
