Fallback to system font if Wimp$Font is unset

If the configured desktop font is 0 (use Wimp$Font) but that variable is unset, use system font instead like the Wimp does rather than failing to get a font handle from Font Manager.
Refactor the extraction of configured font from CMOS using bitshift and mask future tech.
