The unit of nsCSSValue is always number/pixel/percent or eCSSUnit_Calc,
so we don't need the style context for Servo backend.
Besides, ReadTransform is a public API used in many places, so we keep
its argument type as nsStyleContext.

One thing to note here is that the Scale function on gfxRect has a
different implementation than that in gfx::Rect which is replacing it.
The former just scales the width/height directly whereas the latter
scales the XMost/YMost and recomputes the width/height.

This also moves the WithinEpsilonOf function from gfxPoint into
PointTyped, and changes call sites that are using
gfxPoint::Transform(Matrix4x4) to use Matrix4x4::TransformPoint(Point)
instead, which should be equivalent.

Use Servo backend to decompose/interpolate/recompose matrices on both
main thread and compositor thread.
Note: Due there may be differences in precision used to represent the
components, and the computation of matrix interpolation are not
exactly same (still following the formulas in spec). There are some
tiny differences between the interpolation results of 2d/3d
matrices on Gecko and Servo, especially if there is skew() or any 3d
transform function.

Move the common part of GetScaleValue into nsStyleTransformMatrix, and add a
new method, GetScaleValue, on AnimationValue, which can get the scale value from
StyleAnimationValue or RawServoAnimationValue.

Decompose the 2d/3d matrix and calculate the Euclidean distance of
translate, scale, skew, quaternion, and perspective vectors.

Move Decompose2DMatrix and Decompose3DMatrix into nsStyleTransformMatrix
and remove some trailing spaces.
Both AddWeighted and ComputeDistance need Decompose2DMatrix and
Decompose3DMatrix on transform property, and both decomposition functions are
related to nsStyleTransformMatrix, so we move them into nsStyleTransformMatrix
to make StyleAnimationValue more concise.

Reuse AddTransformLists to get the identity transform functions to
replace none, and then treat them with another transform list as two matched
ones.

This patch also moves the static methods defined on nsStyleAnimation so that
they are part of StyleAnimationValue class.
Renaming nsStyleAnimation.h to StyleAnimationValue.h is performed in a separate
patch to simplify the diff (since some tools may not handle file renames
elegantly).
