Revert 212794 "Migrate users from "WebKit" flag to "Web Platform"."

> Migrate users from "WebKit" flag to "Web Platform".
> 
> We changed the name of the "Experimental WebKit Features" flag, and changed
> the actual flag at the same time[1]. I decided at the time to simply throw away
> the old flag; I've been reliably informed that developers aren't particularly
> thrilled with that decision. "Why have my experimental features stopped
> working?" they ask. "Didn't you read my G+ post?" isn't a particularly helpful
> answer, especially since most people (unbelievably!) don't follow me on
> The Internets™.
> 
> This patch hacks a migration system into about:flags, which I hope we never
> ever have to use again, and can safely throw away after a release cycle or two.
