This PR is a follow-up to #11248. Although plugin-optional-chaining is applied before transform-classes, the transform-classes plugin works on the Class node, ancestry of the optional chain. It is possible that replace-supers might see super.foo?.() and don't know how to handle that.

This PR adds optionalCall handler, so super.foo?.() will be transformed to

Foo.foo?.call(babelHelpers.assertThisInitialized(this));
