SeaVGABios/cbvga: Advertise compatible VESA modes

Advertise compatible VESA modes, that are smaller or equal to
coreboot's active framebuffer. Only modes that have the same Bpp
are advertise and can be selected.

Allows the Windows 7 bootloader NTLDR to show up in VESA mode.
Allows to show the Windows 7 boot logo.
Allows Windows to boot in safe mode and in normal boot using
VgaSave driver with resolution up to 1600x1200.

This fixes most likely other bootloader and operating systems as well,
in case the are relying on VESA framebuffer support.
