Make the rule tree actually threadsafe
RuleTree::gc is now a safe method that any thread can call
at any time, and StrongRuleNode values can all be dropped
whenever their owner want to, on any thread.

[python/servo/bootstrap.py] Add missing comma

Add a missing comma in `pkgs_dnf` list, so `python3 ./mach bootstrap` works on Fedora.

Unfortunately I can't actually build Servo right now because of lack of RAM (whoops), but hopefully adding a single comma between elements of a list is small enough of a change for you to overlook that. 😅

Always upgrade existing weak child references in the rule tree
Just because we didn't find a child when read-locking a node children list
doesn't mean it still won't exist while we wait to upgrade the read lock
into a write lock to create the child.
Eliminate `AnimationFrame`
This intermediate data structure doesn't really buy us anything and is a
bit confusing.

This implements the easy / straight-forward parts of the :where / :is
selectors.
The biggest missing piece is to handle properly invalidation when there
are combinators present inside the :where. That's the hard part of this,
actually.
But this is probably worth landing in the interim. This fixes some of
the visitors that were easy to fix.
