CC_MEASUREMENT_ENABLE is designed to control the loading of TdTcg2Dxe
driver which is for EFI_CC_MEASUREMENT_PROTOCOL. TdTcg2Dxe is TD-Guest
specific driver.
From the security perspective a TD-Guest shall always load the TdTcg2Dxe
driver so that EFI_CC_MEASUREMENT_PROTOCOL is installed and booting
events are measured and extended to RTMRs.
TdTcg2Dxe will check if it is running in a TD-Guest. If not then it
returns right now and no EFI_CC_MEASUREMENT_PROTOCOL is installed.
