Brian Lewis 3bb211dfa3 servo: Merge #17404 - Shrink rulenode (from zuwow:shrink-rulenode); r=bholley
This shrinks rulenode by one word by removing the Option wrapper around the StyleSource and adding None to StyleSource as an additional variant. The issue mentions shrinking by two words but the free_count one was taken care of in #17368.
