Allow print to work on any set

[tpadioleau]

The PR allows print_type_info, and print, to work for any kind of set of DiscreteElement. This is achieved by passing the extents of each dimension with a DiscreteVector that is common to all sets. A recursion is replaced by a fold expression.

I also took the opportunity to remove some unnecessary template functions making them inline for now.
