TypeScript 4.2 has changed its emitted syntax for synthetic constructors when using `downlevelIteration`, which affects ES5 bundles that have been downleveled from ES2015 bundles. This is typically the case for UMD bundles in the APF spec, as they are generated by downleveling the ESM2015 bundle into ES5. ngcc needs to detect the new syntax in order to correctly identify synthesized constructor functions in ES5 bundles. Fixes #41298 PR Close #41305
