This corresponds to the approach outlined in https://github.com/w3c/csswg-drafts/issues/4822
Specifically:
* Calling play() / pause() always triggers the "animation play state is being
overridden by the API" behavior (unless the method throws an exception).
* Setting the startTime or calling reverse() only triggers this override
behavior if it results in a change between a playState that is paused and a
playState that is not paused.

Currently we avoid posting animation restyles when unbinding an element by
removing the element from the document before deleting its animation
collections. As a result, when canceled animations go to post a restyle, they
can't find a pres context and give up posting a restyle.
However, this is problematic for two reasons:
* It means we can't remove such canceled animations from the
PendingAnimationTracker if they are present there (i.e. it regresses the fix
from bug 1223445).
* It means we can't post cancel events for such animations/transitions since we
can't lookup the appropriate AnimationEventDispatcher.
In the next patch in this series we will change that order to fix the above
problems but before we do that, we need to introduce another mechanism to make
sure that we don't post restyles when unbinding an element or else we will
regress bug 1396041.
This patch does that by introducing a flag which causes us to not post restyles
when we are doing DOM surgery. For all other cases we actually _do_ need to post
restyles in order to update the style correctly.
Without this patch, layout/style/crashtests/1396041.html would fail after
applying the next patch in this series.

CancelNoUpdate actually can and does trigger restyles via its call to
KeyframeEffect::NotifyAnimationTimingUpdated so at very least its name is wrong.
Furthermore, we actually want canceling to trigger restyles in most cases since
when an animation is canceled we need to trigger a subsequent restyle to apply
the (no-longer-animated) result.
This wasn't necessary when CancelNoUpdate was first introduced but since then we
have introduced the Servo style engine where we use a separate traversal to
apply the result from creating/deleting/modifying animations.
This change will mean that we now trigger a "layer" restyle when canceling an
animation when we previously didn't. That, however, seems more correct if
anything.
This patch also makes CancelFromStyle no longer virtual since it doesn't seem
necessary anymore (perhaps because we now point to the concrete type:
CSSAnimation/CSSTransition from nsAnimationManager/nsTransitionManager whereas
previously we didn't).

This is more consistent with what the Rust bits of the style system do, and
removes a pointer from ComputedStyle which is always nice.
This also aligns the Rust bits with the C++ bits re. not treating xul pseudos as
anonymous boxes. See the comment in nsTreeStyleCache.cpp regarding those.
Can't wait for XUL trees to die.

Now we sort CSS animation/transition events by scheduled event time prior
to compositor order.

In a subsequent patch in this patch series, we want to make nsPresContext
have an AnimationEventDispatcher as RefPtr<>.
Instead, if we were trying to make nsPresContext have the
AnimationEventDispatcher as data object (not RefPtr<>) just like we did in
CommonAnimationManager, we will fall into header inclusion hell since Element.h
includes nsPresContext.h and AnimationEventDispatcher.h ends up including
Element.h. Even if we could solve the inclusion hell, we will suffer from Rust
bindgen issues for some reasons.

Now single AnimationEventDispatcher can handle both CSS animation/transition
events simultaneously. To do this we had to change AnimationEventInfo and
TransitionEventInfo into a single struct, the struct is also named
AnimationEventInfo.
It results we can sort both CSS animation/transition events altogether. Thus
we make sure CSS animation/transition events are sorted by scheduled event time
prior to their composite order (i.e. transitions is prior to animations).
At this moment, we don't sort both events altogether since nsAnimationManager
and nsTransitionManager has an AnimationEventDispatcher respectively. In the
next patch we move AnimationEventDispatcher into nsPresContext, i.e. each
document has an AnimationEventDispatcher without the distinction between
CSS animations and transitions.
Note that, after this patch, we copy all members in InternalTransitionEvent and
InternalAnimationEvent in the copy-constructor of AnimationEventInfo, this
will be fixed once WidgetEvent has move-constructor and move-assignment
(bug 1433008).

Only animationcancel event uses current time, the elapsed time for other
animation events are simply calculated from given animation properties (e.g.
animation-duration, animation-delay, etc.), so they should not be reduced the
precision.

In summary, we are splitting the "pending" play state out into a separate
boolean member so that it is possible to distinguish between "play-pending" and
"pause-pending" and because most of the time when you check for
animation.playState === 'running' you also really want to include play-pending
animations.

For every file that is modified in this patch, the changes are as follows:
(1) The patch changes the file to use the exact C++ mode lines from the

(2) The patch deletes any blank lines between the mode line & the MPL

(3) If the file previously had the mode lines and MPL boilerplate in a
single contiguous C++ comment, then the patch splits them into
separate C++ comments, to match the boilerplate in the coding style.
