Nobody defines SK_SUPPORT_HINTING_SCALE_FACTOR any more, so remove it.

I left the dummy value in the flattened paint.  I'm hoping to do an overhaul of
the paint serialization format which will need a picture version bump anyway,
so it can all go together.  If that doesn't pan out we can remove this on its
own later.
