fix(ivy): generate explicit type annotation for NgModuleFactory calls in ngfactories (#30708)

Prior to this commit there were no explicit types setup for NgModuleFactory calls in ngfactories, so TypeScript inferred the type based on a given call. In some cases (when generic types were used for Components/Directives) that turned out to be problematic, so we add explicit typing for NgModuleFactory calls.
