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.

Cf. https://edk2.groups.io/g/devel/message/76337
