pangowin32: Use DirectWrite to enumerate system fonts
...instead of using EnumFontFamiliesEx(), and retrieve the LOGFONTW's that we
need via DirectWrite's GDI interop. Also cache up our IDWriteFont's that we
obtained, so that we can use DirectWrite to query font properties better
than what GDI/Uniscribe can do for us, such as obtaining stretch info from
the font. Also update synthesize_foreach() accordingly, since we should
also record the IDWriteFonts as well for synthesized LOGFONTWs.
Portions based on Luca Bacci's implementation of the DirectWrite fontmap
support in the upcoming Pango2.
