Remove SkTypeface::Style use in API.

All known callers of SkTypeface::MakeDefault call it with kNormal and
the only users specifying kNormal explicitly are in Skia, so remove the
parameter. There appear to be no users of SkTypeface::MakeFromTypeface,
so remove it. The current alternative is SkFontMgr::matchFaceStyle which
can do a better job anyway.
