Move font related data structured to sys/font.c and update vtfontcvt
Prepare support to be able to handle font data in loader, consolidate data structures to sys/font.h and update vtfontcvt. vtfontcvt update is about to output set of glyphs in form of C source, the implementation does allow to output compressed or uncompressed font bitmaps.

The binary font file is for use by
