Fabric: pointScaleFactor is now part of LayoutContext and LayoutMetrics

Browse Source 
Summary:
@public
... and we initalize this in Surface.
We need this for requesting images with proper size/pixel-density, setup proper parameters for rasterizing CALayer's and rounding layout metric values.
Then we have to figure out how to wire this up with YGConfig.
