Add globally-unique HistoryItem identifiers (and have WebKit2 adopt them)

With process swapping, the WebKit assumption that "back/forward items belong to a process" has been invalidated.

So we need to uniquely identify all history items across all processes so there will never be a collision in the global UIProcess namespace.

This also lets us get rid of the "per-WebProcess WebBackForwardListItem registry"
