Improve alternate maps display in rando

[GSKirox]

There are four instances in OoT where the range of the map displayed at the bottom is dependent on certain flags that don't really make sense in rando anymore.
These four alternate maps are Gerudo Valley, Gerudo Fortress, Graveyard and Lake Hylia.
See the relevant code in decomp.

• Valley works fine since it's just showing the bridge if it's been rebuild.

• Graveyard is dependent on getting Nocturne, but several Entrance rando settings can get you to the warp pad without needing it, so probably best to just always show the extended one.

• Fortress is dependent on freeing the carpenters, but in rando it would be better to be on getting the Gerudo Card.

• And Lake Hylia is tied to getting the Water med, when it should be looking at the water raised flag that you can switch with the custom Gossip Stone.

For reference, OoTMM has an implementation of this change: this commit for Graveyard/Fortress and this one for Lake (thanks Nax!).
Note that the Fortress one just always show the extended map instead of looking at the Card.

A quick fix would be to override the conditions, but if we really want to polish this feature, we could also force the minimap to refresh if e.g. the Gerudo card is collected while in fortress. Depends on how complicated that would be to implement of course.
