Pokémon R/B: Door Shuffle fixes

[Alchav]

What is this fixing or adding?

• Fixes an issue where collecting an item to check whether it adds reachable entrances during entrance shuffle causes a sweep for events with that item which can collect items into the state that remain collected, which can cause regions to appear reachable during door shuffle that shouldn't. This affects Full and Insanity door shuffles.
• Fixes an issue where placing Cascade Badge in Celadon Gym is prevented only when badges_needed_for_hm_moves is on but not when it is set to extra. Affects all door shuffle options.
• Fixes the Celadon Gym gym leader being in the Celadon Gym region instead of Celadon Gym-C (The central area of the gym which requires Cut). This could erroneously put passing the Route 3 guard in logic.
• Adds the Route 23 door for the exit from Victory Road to the list of unreachable outdoor entrances so that it ensures it is connected to before running out of doors (the Pokémon League door is always a Pokémon Center and thus always a dead end).
