Pete Bacon Darwin f16ca1ce46 build(docs-infra): correctly handle "pseudo" classes (#36989)
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.
