If no valid boot options were found, PlatformBootManagerLib refreshes a set of sane default options and then reboots. However, if there is in fact no persistent varstore, the same thing happens again on next boot, and we end up in an endlessly rebooting loop. So when PcdEmuVariableNvModeEnable is TRUE, skip the reboot step and enter the setup menu instead.
