    grub-efi-cfg: enable per-label APPEND override
    
    For legacy bios boot configurations, syslinux supports multiple
    labels with per-label APPEND definitions.  grub-efi-cfg supports
    multiple labels, but only a single APPEND definition.
    
    Enable optional per-label APPEND definitions for grub EFI, with
    variable names prefixed by "grub_" to isolate grub definitions from
    syslinux defintions.
    
    Example use from an ISO image recipe that inherits grub-efi-cfg:
    
     LABELS_LIVE="foo bar"
     APPEND_grub_foo = "linuxcmdline"
    
    No change in behavior for those using APPEND without overrides.
