Greg Daniel c52db71c9b Store GrSurfaceProxyViews on SkSpecial*_Gpu. 
To make this change cleaner, GrMakeCachedBitmapProxy now returns a view
and all its callers updated.

Additionally some effects were updated to fully use views in cases
where they had to be updated anyways to support SpecialImages and there
wasn't much additional work to pass them around everywhere.
