Label BattleTowerRoomMenu

All of the functions called by it are prefixed with BattleTowerRoomMenu,
but a bunch of them seem more generic than that, since they're part of
different mobile menus. Also called another menu jumptable
BattleTowerRoomMenu2 for the lack of a better name (only the Yes/No menu
functions are used in western crystal).
The names of the more generic functions should be fixed when we start
labelling other menus.
