Description
As discussed in #31249, a lazy implementation of charts or transition maps comes in handy in some situations as the number of transition maps explodes very easily.
In this ticket, we introduce a lazy implementation of transition maps that only initializes most attributes, especially the associated MultiCoordFunction
and the inverse, if necessary.
