This commit handles "subclass: super-interface by delegate-expression". During Psi2Fir, for each delegate, we add to the subclass a synthetic field (which has type super-interface), and an assignment of the delegate-expression to the synthetic field in the primary constructor, so that the delegate-expression can be resolved and transformed along the way. During Fir2Ir, we look up delegatable members from the super-interface and generate corresponding functions/properties for the subclass. TODO: support for generic delegatable members and generic super-interface.
