This version of the Dynamic Toolbar moves the animation of the toolbar
from the Android UI thread to the compositor thread. All animation for
showing and hiding the toolbar are done with the compositor and a static
snapshot of the real toolbar.

This augments the AnimationMetricsTracker to also track compositor animations
triggered by chrome and content layers separately. During the animation, the
tracker keeps a count of frames composited, and once the animation ends, it
uses the wall-clock time and vsync interval to compute the expected number of
composited frames. It then submits a ratio of actual/expected to telemetry.
A score of 1000 (because the ratio is scaled up to an integer between 0 and 1000)
indicates a perfect score with no frames dropped. Lower values are worse, and
values significantly above 1000 indicate abnormal behaviour. Values may be slightly
above 1000 due to rounding error or vsync jitter.

This allows the AsyncCompositionManager to know whether compositor animations
are coming from chrome layers or content layers (using the rootmost RefLayer
as the boundary). This information is needed to have the compositor animation
telemetry probes separate information by chrome/content.

If all of animations on an element are paused, finished or zero playback rate,
we don't send those animations to the compositor.
Also in this change, we send zero active duration animations to the compositor
in the same way as normail animations.

We need to consider fill mode in compositor thread as well as other properties
because pulling the animation back from the compositor thread is sometimes
delayed due to the main thread busyness. In such situations, if there is
another animation running on the main thread on the same element, users can
easily notice a gap between both of animations.

The check of negative elapsedDuration is basically no longer valid since
animation delay is not factored into start time any more. But still we have
somtimes met negative elapsedDuration sice we use a previous vsync time stamp
for async animations to make the animations more sync. This is not a problem
in most cases but makes two reftests intermitent failure because both of them
used steps(1, start), the steps(1, start) composed different results in the
before phase and in the active phase. To avoid this difference this patch
replace the steps(1, start) with steps(1, end).
Once we incorpolate playbackRate into GetCurrentOrPendingStartTime, we don't
need to call AnimationTimeToTimeStamp for deviding delay by playbackRate since
the time passed to AnimationTimeToTimeStamp does not contain delay any more.

Add AndroidCompositorWidget to act as the intermediary between gfx code
and GeckoLayerClient, in place of AndroidBridge. AndroidCompositorWidget
currently inherits from InProcessCompositorWidget, but when Android
eventually supports OOP compositing, it will be made to inherit from
CompositorWidget directly.
It would make the next change awkard.
This also temporarily removes the current, incomplete, handling of an
unconsumed translation, but this will be added back (and made complete)
in the next commit.

There shouldn't be a local transform because we create container layers
for fixed layers, so any transform would be on a descendant layer instead.

This implements the spec change in 21de090dac
The spec change refers to a binary 'animation direction' flag. Instead of that,
however, we just pass the playback rate along and use it inside
GetComputedTimingAt since this seems simpler.
Also, this patch moves the implementation of
KeyframeEffectReadOnly::GetComputedTiming from the header file into the .cpp
file. This is because with this change, GetComputedTiming needs to call
mAnimation->PlaybackRate() and so mozilla::dom::Animation needs to be a complete
type. However, simply including Animation.h doesn't work because of a cyclic
dependency between KeyframeEffect.h and Animation.h. We might be able to fix
this later but since yet-to-land bug 1049975 moves this code around a lot, I'd
rather not touch it too much just now.
