When a compositor animation finishes that doesn't apply a fill, rather than
jumping back to the underlying value immediately we should apply a fill mode
until the main thread has a chance to remove the animation from the compositor.
This ensures that any main thread effects that are intended to synchronize with
the end of the animation have a chance to run before we show the underlying
style and helps to avoid flicker in such cases.
Currently we apply this synthesized fill mode to animations when they run
forwards (i.e. positive playback rate), but not backwards. This patch makes us
apply the same handling when running in reverse.

On the compositor we store animation values in a hash table and the hash is
the compositor animation id which is a unique id for each property respectively.
So we can get the corresponding animation value for the given property.
In this patch there are lots of duplicated code, but they will be removed in the
next patch.

This was done automatically replacing:
s/mozilla::Move/std::move/
s/ Move(/ std::move(/
s/(Move(/(std::move(/
Removing the 'using mozilla::Move;' lines.
And then with a few manual fixups, see the bug for the split series..

If the animation is in delay phase, we shouldn't produce any values for the
animation but we have to make sure subsequent ticks happen in order to the time
when the animation starts. So what we should do here is that
1) Make AnimationHelper::SampleAnimations() return boolean, return true if
there is any animation.
2) Schedule the next tick if AnimationHelper::SampleAnimations return true
This setup is equivalent to what we do non-WebRender.
So that we don't need to set non-animated value as AnimatedValue for delay
phase to make subsequent ticks happen for the delay phase animations. The
non-animated value will be dropped in the next patch.

When we send play-pending animation to the compositor, we resolve its start
time with the time at the very moment we send the animation to the compositor
instead of refresh drivers' tick time. That means that it's possible that the
start time indicates more future time stamp than the previous frame time stamp
on the compositor. If we were to use the previous frame timestamp in this
case, then we'd end up treating the animation as if it had not yet started so
we would skip its initial paint.

Before this change, the value which was set by SetShadowBaseTransform()
has been used for the assertion, but it is possible that the value is changed
by APZ. And it's hard to tell whether the value has been changed by APZ or not
and it's hard to *reverse-calculate* the differences in the past APZ at the
moment we want to do the assert.
So after this patch, on debug build we don't actually skip the calculation for
unchanged animations and use the newly calculated value for the assertion.

Note that we have to calculate animation values if there is another animation
since the other animation might be 'accumulate' or 'add', or might have a
missing keyframe (i.e. the calculated animation values will be used in the
missing keyframe).

We don't need to calculate TimingParams each time we compose an animation on
the compositor because TimingParams is immobile since the animation was sent to
the compositor.

Two AnimationValue are still used in AnimationPropertySegment since the
AnimationPropertySegment is used in compose_animation_segment() which is also
invoked on the main-thread, so we will fix it later in a bug that will drop
AnimationValue usage on the main-thread side.

This is slightly efficient since we don't need to call
GetBaseAnimationStyle() or we do skip allocating animation data for such case.

I can propagate the error up if needed, but looks like the code should cope with

We want to always use Servo animation backend on the compositor.
However, Android doesn't support Stylo now, so add a defined flag for it.

We get the progress as |double|, and then pass it to a function by a |float|
type, and then finally cast it back to |double| for the interpolation.
We should avoid casting it back and forth, so change the function argument to
use |double| type for the progress.

We are seeing occasional failed release assertions from calling
animation.startTime().get_TimeDuration() in SampleAnimationForEachNode on
Windows.
My theory is that in some circumstances (perhaps graphic-driver related?) when
creating a layer transaction we fail to call Layer::StartPendingAnimations and
end up sending pending animations to the compositor. Prior to bug 1334583 that
would have only triggered a debug assertion so it may have gone unnoticed if it
depends on the system configuration.
This patch makes us check that the startTime is set before we try to access it
in order to avoid triggering a release-time assertion. If the startTime is not
set we will use the hold time which should give us the correct behavior for
a still-pending animation. (Furthermore, the holdTime is set unconditionally
when we create animations so it should be correct -- but even if it were not
set explicitly, its initial zero value would still likely produce a reasonable
result until the start time was updated on a subsequent layer transaction. At
very least, it should not crash. Likewise, if it was set to an incorrect value.)
This patch also strengthens the debug assertion in SampleAnimationForEachNode to
check that not only is start time not-null, but that it is set to a TimeDuration
since MaybeTimeDuration also includes a third uninitialized "None" state.
