[vesafb] Add VESA frame buffer console

Browse Source 
The VESA frame buffer console uses the VESA BIOS extensions (VBE) to
enumerate video modes, selects an appropriate mode, and then hands off
to the generic frame buffer code.

The font is extracted from the VGA BIOS, avoiding the need to provide
an external font file.
