Do not create a stacking context for CSS clip

This patch extracts out the stacking context grouping properties from
ComputedStyle::HasGroupingProperty, and uses this for the stacking
context decision. This has the effect of not creating a stacking context
for clip which, unlike clip-path, does not create a stacking context:
