Let LayoutView::StyleWillChange handle viewport invalidation.

Make sure we only do a single SetStyle for viewport ComputedStyle
to which we propagate certain documentElement/body styles. That way we
can do style invalidation diffing on SetStyle. The invalidation will
now be done on LayoutView::StyleWillChange instead of invalidating
LayoutView from LayoutBox::StyleWillChange for documentElement and body
changes.

The LayoutView invalidation does still use a limited repaint based on
propagated background changes.
