Hardware accelerated CSS transitions appear pixelated when scaled up using transform

Take transforms and animations into account when computing the contentsScale
for a layer, so that scaled-up layers remain sharp most of the time.

In its recursiveCommitChanges() tree walk, GraphicsLayerCA now tracks
a root-relative transform, and extracts from that transform the X and Y
scales which it uses to scale the backing store.

If the layer has transform animations on it, we keep around
a transformation matrix for the animation endpoints (or keyframes),
pick up the state that has the larger impact on the root-relative scale,
and use that as the layer's transform, and the transform when recursing
over descendants.

Tests: compositing/contents-scale/animating.html
       compositing/contents-scale/scaled-ancestor.html
       compositing/contents-scale/simple-scale.html
       compositing/contents-scale/z-translate.html

* platform/graphics/ca/GraphicsLayerCA.cpp:
(WebCore::maxScaleFromTransform): Decompose the transform if necesssary
to extract the X and Y scale components.
(WebCore::GraphicsLayerCA::GraphicsLayerCA): Initialize m_rootRelativeScaleFactor.
(WebCore::GraphicsLayerCA::flushCompositingState): Supply a TransformationMatrix
for the root of the recursion.
(WebCore::GraphicsLayerCA::layerTransform): This code was factored out of
computeVisibleRect(), and optionally takes a custom transform.
(WebCore::GraphicsLayerCA::computeVisibleRect): Use the layerTransform() function.
(WebCore::GraphicsLayerCA::updateRootRelativeScale): Given a transform from the root,
find the max scale factor by multiplying the various animation endpoint matrices and picking
the one with the biggest impact on scale. Use this to set m_rootRelativeScaleFactor, and
set the flag to say that we need to update contentsScale.
(WebCore::GraphicsLayerCA::recursiveCommitChanges):
(WebCore::GraphicsLayerCA::commitLayerChangesBeforeSublayers): After updating
animations, call updateRootRelativeScale() to update m_rootRelativeScaleFactor.
(WebCore::GraphicsLayerCA::updateAnimations): We have a side table of animation name to
TransformationMatrix, so figure out which entries can be removed from that side table,
and remove them.
(WebCore::GraphicsLayerCA::setAnimationOnLayer):
(WebCore::GraphicsLayerCA::appendToUncommittedAnimations): Store the matrices for
animation endpoints/keyframes in the m_animationTransforms side table. We don't store
them directly in LayerPropertyAnimation because we just want the final matrix for
a transform list, and using a side table makes ownership easier to manage.
(WebCore::GraphicsLayerCA::getTransformFromAnimationsWithMaxScaleImpact):
goes through the matrices for the running animation endpoints/keyframes, and
multiplies each with the transform up to this layer to find the matrix with the
larger impact on scale.
(WebCore::GraphicsLayerCA::setTransformAnimationEndpoints): Returns a vector
of TransformationMatrix for the from and to states.
(WebCore::GraphicsLayerCA::setTransformAnimationKeyframes): Returns a vector
of TransformationMatrix for the keyframes.
(WebCore::GraphicsLayerCA::updateContentsScale): Include m_rootRelativeScaleFactor in the
scale factor computation.
(WebCore::GraphicsLayerCA::dumpAdditionalProperties): If we're dumping visible rects,
also dump the contentsScale. Convenient at these are useful to look at together, and I didn't
want to pollute Internals with yet more flags.

This was a latent bug that can't actually occur in ToT. It was uncovered by causing slow
