[FIR] Make own accept methods of FirTypeParameterRef inheritors

This change is necessary in order to make `FirElement` abstract class. To do it we need to remove all `accept` and `transform` methods from fir interfaces. So we have to make sure that all fir element implementations have their `accept` and `transform` implementations in their super classes. In particular this change makes 'accept' and 'transform' methods in `FirConstructedClassTypeParameterRef` and `FirConstructedClassTypeParameterRef` base classes.
