Revert 167917 "Change FontFallbackWin to use FamilyNameIterator"

May have caused many crashes on Win layout test bots.

> Change FontFallbackWin to use FamilyNameIterator
> 
> Change the windows font fallback code to use SkTypeface and
> createFamilyNameIterator to check whether a font exists instead of
> calling GDI directly. This removes the last use of HFONT for DW builds
> and supports fonts with locale dependent names.
