(recompute_cached_metrics): Change font arg to w32font_info.

Compute options separately.
(w32font_open_internal): Set glyph_idx before caching metrics.

* w32font.c (recompute_cached_metrics): Change font arg to w32font_info.
Compute options separately.
(w32font_open_internal): Set glyph_idx before caching metrics.
* w32font.h (NTM_PS_OPENTYPE, NTM_TT_OPENTYPE, NTM_TYPE1): Define
if system headers don't.
(struct w32font_info): Enlarge ascii_metrics. Add glyph_idx.
