ConditionSet

[mkoeppe]

(from #24176).

We define a class ConditionSet for subsets of elements given by a logical "and" of finitely many predicates.

If the given predicates (condition) are symbolic, a ConditionSet can be converted to a SymPy ConditionSet; the _sympy_ method falls back to creating a SageSet wrapper otherwise.

As an application, we provide Chart and RealChart with a method codomain.

Depends on #32013
