cc: Pass the device and page scale factor to CalculateContentsScale
The page scale factor affecting a layer is only known by LayerTreeHostCommon,
as the scale factor does not always affect the whole tree, but instead some
subtree. If a picture layer found itself outside the page scale subtree, it
would use the wrong page scale in its computation if it used the value found
on LayerTreeImpl.
Also passes along the device scale for symmetry and to make the data flow as
clear as for page scale.
