Document BaseRoom, JoinedRoom, NotJoinedRoom, RoomAliasHelper and JoinRoom,
along with their members, and add the missing @param entries.
Fix the documentation of BaseRoom.getUpdatedIsEncrypted, which described the
room directory visibility instead of the encryption state it actually returns.
Behaviours taken from the implementations: BaseRoom.predecessorRoom swallows
errors into null, updateMembers only reads the cache on its first call,
JoinedRoom.syncUpdateFlow is an opaque change counter, notification settings
start in an Unknown state until updateRoomNotificationSettings is called, and
JoinRoom maps a Forbidden answer to Failures.UnauthorizedJoin.
