pangowin32: try harder to load a font
load_fontset() in pangowin32 has various fallback code in case
no font is found, but load_font() doesn't and just returns NULL
in more cases.
I saw that the other backends like fc and coretext just call
load_fontset() in load_font() and return the first one.
This copies this strategy to the win32 backend.
