fix(ngcc): detect synthesized delegate constructors for downleveled ES2015 classes (#38463)

Similarly to the change we landed in the `@angular/core` reflection
capabilities, we need to make sure that ngcc can detect pass-through
delegate constructors for classes using downleveled ES2015 output.

More details can be found in the preceding commit, and in the issue
outlining the problem: #38453.

Fixes #38453.
