[GeckoView] Skip fetching/parsing of pageLabels

Browse Source 
Currently there's no toolbar in the GV-viewer, hence invoking the pageLabels functionality isn't meaningful and just leads to unnecessary parsing on both the main- and worker-threads. (And if a toolbar is added at some point, it's not clear to me if we'd want to support pageLabels in the GV-viewer anyway.)
