This patch implements the `FontFace` interface, but with some caveats 1. The interface is only exposed on `Window`. Support for Workers will be handled in the future. 2. The concept of `css-connected` `FontFace` is not implemented, so `@font-face` rules in stylesheets will not be represented in the DOM. 3. The constructor only supports using `url()` strings as source and `ArrayBuffer` and `ArrayBufferView` are not supported yet. A skeleton implementation of the `load` method of `FontFaceSet` is also implemented in this patch. The intention is to support some web pages that don't load without this method.
