Move SkScalerContext_DW::fIsColorFont to typeface.

Browse Source 
There is no advantage to having every SkScalerContext_DW recompute and
store fIsColorFont when this is a constant on the typeface. Have the
typeface compute the value once and store and have the scaler contexts
look it up on the typeface.
