Itanium support has been removed from EDK2 aroun 2019.
ITANIUM_HANDOFF_STATUS data structure looks to be
some leftover from that process.
There is also positive sidefect of this data structure removal.
Due to HOB allocation type used in PEI stage there is a limit
how much data about virtual CPU can be hold. This limit result
in only 1024 vCPU can be used by VM.
With Itanium related data structure removed more allocated space
can be used for vCPU data and with current allocation limit
will change from 1024 to around 8k vCPUs.
