ForAnimationOnly is somewhat misleading, it means actually we process
*only* animation-only restyle without normal restyle. The purpose of
ForAnimationOnly is for updating throttled animations to get correct position
of the animations when we need to handle events. Currently we do also update
unthrottled animations though.

Before this refactoring, getComputedStyle could have side effects, and left the
style data in the element, so we could never arrive there without data.
There are a few crashtests that caught this, but this was already broken if you
called animate() on an element deep in a display: none subtree.

We need to call nsBindingManager's method from ServoStyleSet in a later
patch.
Also, we call nsStyleSet::SetBindingManager() immediately after we call
nsStyleSet::Init(). Therefore, we could pass binding manager to Init()
directly, and delete SetBindingManager().

This commit adds class ServoStyleRuleMap which caches the mapping from
raw Servo style rule to Gecko's wrapper object.
It is a per-document object, and is added as an observer of document
when constructed, so that it updates data inside when possible.
For safety consideration, this change also makes ServoStyleRule support
weak pointer, and use weak pointer inside ServoStyleRuleMap.

It was getting inial value from gecko side before and that was always
eCompatibility_NavQuirks. Created an FFI to fetch quirks mode.

In next part, we'll use ServoStyleSet to host XBL stylesheets. The raw set
is not available until the resources are loaded, so it's easier to tell that
by checking whether the pointer is nullptr or not.

We can get the parent style from element tree in servo side.
The parent style has been already restyled.
E.g.;
When we get target element style with nsComputedDOMStyle::GetStyleContext,
the function flushes styles so that the parent style has also
restyled.
When we call Servo_GetComputedKeyframeValues, it's called from a
SequentialTask, that means all elements have been already restyled.
Unfortunately we can't assert that the parent style is not stale
to check the parent element has no dirty descendant bit since
Servo_GetComputedKeyframeValues is called in a SequantialTask
that is processed before post traversal, that means elements
still have the dirty bit to update nsStyleContext in the
post traversal.

I plan to use it for now to force a full document restyle when a standalone rule
changes or something like that.
In practice, we can do better sometimes, and we may just want to propagate to
the StyleSet all the style change notifications in order to have access to the
rule that changed and all that...
But for now this seemed easier than adding other four or five functions to
StyleSetHandle.
