graphics: make use of syslinux_force_text_mode()

The syslinux_force_text_mode() function used in library
space made unnecessary INT 0x22 call that could be simply
used with vgaclearmode() function.

This patche renames vgaclearmode() to
syslinux_force_text_mode() as this naming is generally more
carefully considered and gets rid of "forcetext.c" source
file.

Also all the VGA-related functions and variables that were
exported in core/include/bios.h have been moved out to
core/include/graphics.h which makes more sense actually.
