Message:

grub-setup: rewrite the description for CONFIG_EFI_STUB

Avoid mistakenly using the terminology "EFI handover protocol". With
Linux 6.2 or newer we can enable EFI stub but disable EFI handover
protocol (CONFIG_EFI_HANDOVER_PROTOCOL=n). The help message of this
option also says the upstream GRUB does not use EFI handover protocol,
so it's only needed for some distros with a patched (old) GRUB.

Tested with mainline kernel and CONFIG_EFI_HANDOVER_PROTOCOL disabled.
