"canCrossRoomJumpIntoWater"

Dev note: We don't consider side platforms in rooms where the doorway has a 2-tile runway or more, since in that case getting up using the doorway runway can be done itemless relatively easily, whereas using the side platform would be difficult because of the obstruction.
