The commits a9d1fb58 and ae7e5477b555 caused SCT BS.CreateEvent failures.

Section 7.1 of the UEFI Spec states that TPL_HIGH_LEVEL is designed for
exclusive use by the firmware. The creation of events by UEFI
applications, UEFI drivers, and UEFI OS Loaders should not use this TPL
level.

Therefore, revert TPL_HIGH_LEVEL change in commits a9d1fb58 and
ae7e5477b555 to not create event with TPL_HIGH_LEVEL to be compliant
with UEFI Spec and fix the failures.
