Handle nested properties in JSDoc @typedef

[fongandrew]

TypeScript Version: 2.7.0-dev.20171116

Code

/**
 * @typedef {Object} App
 * @property {String} name
 * @property {Object} icons
 * @property {String} icons.image32
 * @property {String} icons.image64
 */

/** @type {App} */
const app = {
	name: 'name',
	icons: {
		image32: 'x.png',
		image64: 'y.png' 
	}
};

Expected behavior: No error.

Actual behavior: Error. TypeScript treats the above typedef as defining something like this:

interface App {
  name: string;
  icons: any;
  image32: string;
  image64: string;
}

When what we really want is this:

interface App {
  name: string;
  icons: {
    image32: string;
    image64: string;
  }
}

The @property {type} parent.nestedProp syntax can be found here (http://usejsdoc.org/tags-property.html). TypeScript currently supports a similar syntax when used with @param but not with @property.

@mhegazy This isn't a duplicate. #7429 concerns the use of @param with dotted names. This PR concerns the use of @property. As of 2.7.0-dev.20171116, the former works but not the latter.
