efi_loader: TPL_HIGH_LEVEL not allowed for CreateEvent
According to chapter 7.1 "Event, Timer, and Task Priority Services"
TPL_HIGH_LEVEL should not be exposed to applications and drivers.
According to the discussion with EDK II contributors this implies that
CreateEvent() shall not allow to create events with TPL_HIGH_LEVEL.
