Allow read of ChangeDetectorRef in queries

🐞 bug report

Affected Package

The issue is caused by package @angular/core

Is this a regression?

I don't think so, tested on Angular 7 and 8

Description

Through `read` option of `ViewChild` we are able to retrieve services from Injector, for example if we add some service to our component's providers, we can read it. We can also read `ElementRef`, for example. However, we cannot retrieve `ChangeDetecotrRef`. We are getting undefined.

Bumped stackblitz versions and it’s still an issue with Angular 12. @pkozlowski-opensource any reason for the special treatment of CDR here? I don’t see this issue passing voting in 20 days 😦
