Use FeaturePolicy to implement iframe[allowfullscreen]

The previous CL (https://crrev.com/719a425c) tried to handle this in fullscreenIsSupported(), which misses the important case where the Feature Policy API is enabled, but the site uses 'allowfullscreen' iframe attributes.

This CL roughly mimics the intended behaviour of feature-policy allowfullscreen, by allowing access to fullscreen in same-origin iframes, and in cross-origin iframes where either a Feature-Policy header or an 'allowfullscreen' attribute is used, and the parent frame allows fullscreen.
