Support JSDoc `@property`

Example code:
MyController.js

// @ts-check
class MyController {
    getWorld() {
        return this.world; // <--- Marked as error
    }
}
angular
    .module('myApp')
    .component('myComponent', {
        bindings: {
            'world': '<'
        },
        controller: MyController,
        template: `<div>Hello {{$ctrl.getWorld()}}</div>`
    });

The this.world is marked as error, as supposed to be. But it is actually pretty annoying, because in angular you need to use quite often those component bindings. I know there's the option // @ts-ignore, but that really pollutes the code and makes it less readable.

An extensions for this would be really useful.

I use this workaround at the moment

// @ts-check
class MyController {
    constructor() {
        this.world = this.world;
    }
    getWorld() {
        return this.world;
    }
}

[...]

I don't like this at all, but better than writing // @ts-ignore.

Is there any other option / workaround?

Copied from original issue: Microsoft/vscode#26192

The issue provides MyController.js as the reproduction, using a JavaScript class with an Angular component binding and a this.world error. Start by reproducing that example and trace the existing JSDoc support; the work is done when an appropriate @property declaration can describe the binding without @ts-ignore.
