16239: Fix Parent._list_from_iterator_cached instead of implementing a new ZZ.list

For consistency with EnumeratedSets category, and as a preliminary
toward just using it, Parent._list_from_iterator_cached now:

- raises a NotImplementedError rather than a value error for an
  infinite parent
- Uses the category Sets().Infinite() instead of the method
  `is_finite` (which might be costly, not implemented, ...) to decide
  whether the parent is infinite or not

With this, it's not necessary anymore to implement ZZ.list.
Fixed all broken doctests.
Trac 15033: add patch for Maxima limit bug
Fix list_plot if input is complex and in SR

To avoid extra computations, we do not try to convert to some
complex field directly. Instead, we just check whether the
input is in the Symbolic Ring.
add some more tests to show SR, CC, reals can be mixed
