<webview>: Implement fullscreen permission for html5 element.requestFullscreen()
We do it in two stages, first a DOM element requests fullscreen inside <webview>,
this fires a permissionrequest to the embedder of <webview> to decide
whether to allow/deny the request. The element goes fullscreen within
the <webview>'s bounds at this point.
The embedder can:
a) allow the request: in this case we perform the second stage, where the
<webview> element in the embedder enters fullscreen (provided that
the embedder has permission to enter fullscreen).
b) deny the request: in this case, <webview> exits fullscreen mode.
Note that b) will cause a flicker and blink interface is required to avoid that.
That is tracked on

Test=
Load a chrome app with a <webview> in it, make the <webview> point to
some site that has html5 fullscreen request, e.g.
youtube.com.
Add an event listener in the chrome app so that it allows <webview> fullscreen, e.g.
<webview>.addEventListener('permissionrequest', function(e) {
if (e.permission === 'fullscreen') e.request.allow();
});
Now perform necessary action to request fullscreen from the <webview>, for the
youtube case, this would be fullscreening the video player.
Check that the element enters fullscreen mode.
