Description

Nested classes are not collapsible/expandable in Visual Studio.

export class ClassA{

    private ClassB = class{
        ...
    }

}

Code inside classB loses this functionality.

Contributor guide

Research direction
Research the folding range implementation in TypeScript's language service. Specifically, examine how `getFoldingRanges` computes folding for class declarations and class expressions. The bug is that class expressions inside a class body lack folding. Trace the code path for class declaration folding and see why nested class expressions are missed.
