grub-efi.bbclass: Add serial and graphics menu options
The syslinux.bbclass already has support for automatically generated serial and graphics menu choices. This patch adds the same concept to the grub-efi menu. That makes it possible to generate a single image which can boot on a PCBIOS or EFI firmware with consistent looking boot options.
