In the API docs, concrete classes do not list the "implementation" overload on a method, since this is not strictly part of its API.
We recently fixed the rendering of interfaces to display all the overloads, since there is no "implementation" overload.
This commit also fixes the rendering of "pseudo-classes", which are a combination of an interface
and a constant.
Fixes#43001
PR Close#43734
In the code base there are cases where there is, conceptually, a class
that is represented by a combination of an `interface`
(type declaration) and a `const` (value declaration).
For example:
```
export interface SomeClass {
count(a?: string): number;
}
export const: SomeClass = class {
someMethod(a: string = ''): number { ... }
};
```
These were being rendered as interfaces and also not
correctly showing the descriptions and default parameter
values.
In this commit such concepts are now rendered as classes.
The classes that are affected by this are:
* `DebugElement`
* `DebugNode`
* `Type`
* `EventEmitter`
* `TestBed`
Note that while decorators are also defined in this form
they have their own rendering type (`decorator`) and so
are not affecte by this.
