Andreas Kling 646b37d1a9 LibWeb: Cache CSS rules in buckets to reduce number of rules checked 
This patch introduces the StyleComputer::RuleCache, which divides all of
our (author) CSS rules into buckets.

Currently, there are two buckets:
- Rules where a specific class must be present.
- All other rules.

This allows us to check a significantly smaller set of rules for each
element, since we can skip over any rule that requires a class attribute
not present on the element.

This takes the typical numer of rules tested per element on Discord from
~16000 to ~550. :^)

We can definitely improve the cache invalidation. It currently happens
too often due to media queries. And we also need to make sure we
invalidate when mutating style through CSSOM APIs.
