boot menu: Add graphics and serial choices

Add override_grub-efi.inc to override "build_efi_cfg" function
from grub-efi.bbclass, in order to add GRUB_GRAPHICS variable
for grub menuentry specific parameters.
Set "console=tty0" for graphic console options for grub
and syslinux, and also "console=ttyS0" for serial.
