Basically, we use the current target scroll position as the ready time for
scroll animations, so we don't need to wait until it gets painted.
In fact, it's unclear whether do we need play/pause pending status for
scroll animations, so we choose the natural way for now, and this should
match other browsers' behaviors.
Note:
We avoid puting the scroll animation into PendingAnimationTracker
in PlayNoUpdate() and Pause(). However, we may still "try" to remove
scroll animations from PendingAnimationTracker in some APIs just in
case if those APIs change the animations from using DocumentTimeline to
using ScrollTimeline. They should be revisited once we expose
ScrollTimeline to JS.

Based on https://github.com/w3c/csswg-drafts/pull/4842, we define
"has finite timeline", which is a timeline that's not monotonically increasing.
We need this to update start time and hold time for scroll-timeline, so
we play scroll-linked animations as we expected, e.g. GetLocalTime() returns
the correct time value from GetCurrentTimeAsDuration().
Known issue: we still have bugs when setting "animation-play-state:paused".
Will do that in Bug 1741255.

This patch focus on the timing computation of animation effects. We have
to compute the correct progress based on the scroll offsets. Now we
simplify the implementation only from 0% to 100%. The test cases will be
added in the last patch once we hook the scroll timeline to the CSS
animation.

The machinery to report janked animations is;
1) Store the partial pre-rendered animation id and the Animation object in a
hashtable in LayerManager
2) Store the animation id in the Animation object as well
3) When we detect jank, we send the animation id to the main-thread via an IPC
call
4) Find the Animation object with the id in the hashtable and update the
Animaiton
5) Whenever the partial pre-rendered Animation stop running on the compositor
i.e. the Animation finished normally, the Animation's target element is
changed, etc. etc., remove the Animation from the hashtable

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).

We use DisplayItemType as the input of HasAnimationsForCompositor, and
nsCSSPropertyIDSet as the input of GetAnimationsForCompositor.
The caller of HasAnimationsForCompositor just wants to check if there is
any compositor animation for a display item, so we can replace it by the
display item, and get the properties from this display item.
However, the caller of GetAnimationsForCompositor may use a subset of
transform-like properties for getting scale factors, or use all the
transform-like properties for sending all transform animations to the
compositor thread.

Summary: Really sorry for the size of the patch. It's mostly automatic
s/nsIDocument/Document/ but I had to fix up in a bunch of places manually to
add the right namespacing and such.
Overall it's not a very interesting patch I think.
nsDocument.cpp turns into Document.cpp, nsIDocument.h into Document.h and
nsIDocumentInlines.h into DocumentInlines.h.
I also changed a bunch of nsCOMPtr usage to RefPtr, but not all of it.
While fixing up some of the bits I also removed some unneeded OwnerDoc() null
checks and such, but I didn't do anything riskier than that.
So that we can use for KeyframeEffect::GetPropertiesForCompositor().

Animation::FlushStyle() gets called only for CSS animations/transitions'
playState changes in JS or ready Promise for CSS animations. In either case
throttled animation state, which is, to be precise, transformed position or
opacity value on the compositor, doesn't affect those results.
The first test case for CSS animations and the first test case for CSS
transitions in this patch fail without this fix.
