This change adds a new API to the `WebView` for capturing screenshots. This makes it possible to: - use the reftest waiting infrastructure via the API easily. - take more than a single screenshot in one Servo run. - take screenshots, but still paint the `WebView` normally prior to the moment that the screenshot is ready, instead of preventing all non-screenshot-ready paints while taking a screenshot. In addition, the previous infrastructure, the `wait_for_stable_image` option is removed completely. Testing: This change is tested by the passing of the WPT tests, as they commonly use the screenshot feature.
