This fixes the staticTemplates errors in Ivy but loses type safety in nested controls. The core of the fix is export type AbstractControl<T> = NgAbstractControl & TypedAbstractControl<T>; which does't lose too much type safety as the FormGroup, etc., override the intersection types with stronger ones.
A small benefit is that non-typed methods do not need to be included here as they will be inherited.
