LibWeb: Use unchecked_append in StyleComputer::collect_matching_rules()

Browse source 
We already grow the "rules to run" vector before appending to it, so we
can actually use unchecked_append() here and avoid the "needs to grow"
checks every time we append to it.

This takes appending from 3% to <1% when loading our GitHub repo.
