Add support for a WKWebView trial

Adds a way for an embedder to indicate whether a user is or is not
eligible for a WKWebView field trial.

Also fixes an issue discovered during trial development where calling
IsFirstRun too early will silently return (and cache) the wrong value,
rather than DCHECKing so that the developer notices that it's too
early to use that API.
