style: Treat 3d translate/scale as 2d if the value can be expressed as 2d.
For the individual transform properties if they spec a value that can be expressed as 2d we treat as 2d and serialize accordingly. We drop Translate::Translate and Scale::Scale, and then rename Translate::Translate3D as Translate::Translate, Scale::Scale3D as Scale::Scale. So now we use Translate::Translate to represent 2d and 3d translation, and Scale::Scale to represent 2d and 3d scale. There is no difference between 2d and 3d translate/scale in Gecko because we always convert them into 3d format to layers (on the compositor thread), so this change makes things simpler.
