Fix computation of whether a type is finite (#6312)
This PR generalizes TypeNode::isFinite / TypeNode::isInterpretedFinite with TypeNode::getCardinalityClass. It then uses this method to fix our computation of when a type should be treated as finite.
Fixes #4260, fixes #6100 (that benchmark now says unknown without an error).
