This allows using GRUB_EFI_TRUE and GRUB_EFI_FALSE with proper type and
value checking. The UEFI 2.10 specification, in section 2.3.1, table 2.3,
says the size of the boolean is 1 byte and may only contain the values 0 or
1. In order to have the enum be 1-byte in size instead of the default
int-sized, add the packed attribute to the enum.
