feat: do not check whether optional type parameters of classes can be inferred

[lars-reimann]

Closes #1084

Summary of Changes

Optional type parameters of classes are now always allowed, even if they can never be inferred from their usage in the constructor.

This is useful to initialize them to some default value upon instantiation and override this value later, e.g. in return types of functions. See #1084 for an example.
