Attempt #2: Expose wasDiscarded after tab discard.
This is needed for Lifecycle API, see:
https://github.com/WICG/web-lifecycle
WasDiscarded is set on RequestNavigationParams on browser side and
passed into to WebURLRequest on renderer side. And later
set on the Document in DocumentLoader::CommitNavigation.
