style: Simplify our setup for font metric queries from style

Browse source 
While looking at moving the flag around I realized that the only reason
we have FontMetricsProvider and co is because we didn't have access to
the per-document font-prefs cache. That's trivial to fix tho, so do
that and simplify the setup for font queries even more.
