Introduces a new migration schematic that follows the given migration plan: https://hackmd.io/@alx/S1XKqMZeS. First case: The schematic detects decorated directives which inherit a constructor. The migration ensures that all base classes until the class with the explicit constructor are properly decorated with "@Directive()" or "@Component". In case one of these classes is not decorated, the schematic adds the abstract "@Directive()" decorator automatically. Second case: The schematic detects undecorated declarations and copies the inherited "@Directive()", "@Component" or "@Pipe" decorator to the undecorated derived class. This involves non-trivial import rewriting, identifier aliasing and AOT metadata serializing (as decorators are not always part of source files) PR Close #31650
