This is a enhancement to support the case when platform firmware doesn’t support Boot Manager Menu. For now, if BootManagerMenu FFS can not be retrieved from FV, BDS core code will still register a boot option for it. Then, this non-functional boot option will still be booted by user's request (like HotKey or Exit from shell) to cause additional boot time and error status code reported. Therefore, it would be good to skip BootManagerMenu boot option registration and then return error status and Invalid BootOption data for this case so that the BootManagerBoot() or other consumers can directly return without doing anything.
