Subject: fix: also propagate fullscreen state for outer frame
When entering fullscreen with Element.requestFullscreen in child frames,
the parent frame should also enter fullscreen mode too. Chromium handles
this for iframes, but not for webviews as they are essentially main
frames instead of child frames.
This patch makes webviews propagate the fullscreen state to embedder.
Note that we also need to manually update embedder's
`api::WebContents::IsFullscreenForTabOrPending` value.
