Windows: Restrict synthesizing of bold to < 750 weight 

When a black font is used, such as Arial Black, it would cause
the font to appear to be rendered twice, particularly at large
point sizes. This is down to the synthesizing of the bold
aspect, however since the font is actually weighted as black
this is not required.
