Currently constructor parameters with union types that contains nullable argument are not being converted properly and result in broken behaviour.
With this change we align the ctor-parameters downlevel transformer to be closer to the NGTSC reflector: https://github.com/angular/angular/blob/master/packages/compiler-cli/src/ngtsc/reflection/src/typescript.ts#L65-L66
This change should also be synced to ng-packagr.
Closes: #17063
