efi_loader: require at least 128 KiB of stack space
The UEFI specification requires at least 128 KiB stack space. Consider this value as a prerequisite for CONFIG_EFI_LOADER. Mention the requirement in the CONFIG_STACK_SPACE description and decribe that the UEFI sub-system uses CONFIG_STACK_SPACE when defining the memory map.
