Report stdvga modes in VBE via int10 (AX = 4F00h)

As all supported graphic adapters are supporting VGA we should
list them in int10 (AX = 4F00h). Also clext.c and bochsvga.c
are haveing a function named like is_XXX_mode() which checks
if its a default VGA mode or a VESA mode. If its a normal VGA
mode stdvga_set_mode() gets called.
