In some cases, e.g. mouse event, we need to request an animation-only restyle
to force flush all throttled animations when we handle an event with
coordinates. This restyle shouldn't trigger a normal restyle, and add a
different traversal flag, TraversalRestyleBehavior::ForAnimationOnly, to check.
We add one FFI, Servo_GetProperties_Overriding_Animation, which calls
StrongRuleNode::get_properties_overriding_animations() to get a LonghandIdSet,
which may override animation properties running on compositor.
Allow -moz-stack-sizing to work in a single direction only.

style: Refactor the cascade function.
The `cascade_primary_or_pseudo` function was nice when we shared more code, but
right now I think it just makes it harder to understand what's going on.
