Itanium support has been removed from EDK2 around 2019.
ITANIUM_HANDOFF_STATUS data structure looks to be
some leftover from that process.
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1560
GitHub: 4e1daa60f5
There is also positive side effect 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.

__FUNCTION__ is a pre-standard extension that gcc and Visual C++ among
others support, while __func__ was standardized in C99.
Since it's more standard, replace __FUNCTION__ with __func__ throughout
MdePkg.
Visual Studio versions before VS 2015 don't support __func__ and so
will fail to compile. A workaround is to define __func__ as
__FUNCTION__ :
#define __func__ __FUNCTION__

With the introduction of the use of _Static_assert, edk2 requires a C11
compatible compiler. Update Include/Base.h to be compliant with C11.
As of C11, the maximum type of an enum is type `int`. Since the UEFI
Specification 2.3.1 Errata C allows either `int` or `unsigned int`, fix
the 32-bit enum check to use a signed int.
Since the UEFI 2.3 Specification only allowed signed int, update the
comment to reference 2.3.1 Errata C where the change was made to allow
unsigned int.

RegisterCpuInterruptHandler did not allow setting
exception handlers for anything beyond the timer IRQ.
Beyond that, it didn't meet the spec around handling
of inputs.
RiscVSupervisorModeTrapHandler now will invoke
set handlers for both exceptions and interrupts.
Two arrays of handlers are maintained - one for exceptions
and one for interrupts.
For unhandled traps, RiscVSupervisorModeTrapHandler dumps
state using the now implemented DumpCpuContext.
For EFI_SYSTEM_CONTEXT_RISCV64, extend this with the trapped
PC address (SEPC), just like on AArch64 (ELR). This is
necessary for X86EmulatorPkg to work as it allows a trap
handler to return execution to a different place. Add
SSTATUS/STVAL as well, at least for debugging purposes. There
is no value in hiding this.
Fix nested exception handling. Handler code should not
be saving SIE (the value is saved in SSTATUS.SPIE) or
directly restored (that's done by SRET). Save and
restore the entire SSTATUS and STVAL, too.

Bugzilla: 3458 - Add support IORT Rev E.d specification updates

The IO Remapping Table, Platform Design Document, Revision E.d,
Feb 2022 (https://developer.arm.com/documentation/den0049/)
introduces the following updates, collectively including the
updates and errata fixes to Rev E, Rev E.a, Rev E.b, Rev E.c:
- increments the IORT table revision to 5.
- updates the node definition to add an 'Identifier' field.
- adds definition of node type 6 - Reserved Memory Range node.
- adds definition for Memory Range Descriptors.
- adds flag to indicate PRI support for root complexes.
- adds flag to indicate if the root complex supports forwarding
of PASID information on translated transactions to the SMMU.
- adds flag to indicate if the root complex supports PASID.
- adds flags to define access privilege and attributes for the
memory ranges.
Therefore, update the IORT header file to reflect these changes,
and also rename the EFI_ACPI_IO_REMAPPING_TABLE_REVISION macro to
EFI_ACPI_IO_REMAPPING_TABLE_REVISION_00.
Also update the IORT generator in DynamicTablesPkg to fix the
compilation errors so that Git Bisect can work.

VariableSmm and VariableStandaloneMM driver in MdeModulePkg need
to use this services but MdeModulePkg can't depend on UefiCpuPkg.
Thus, the solution is moving SmmCpuRendezvouslib.h from UefiCpuPkg
to MdePkg and creating SmmCpuRendezvousLib NullLib version
implementation in MdePkg as dependency for the pkg that can't
depend on UefiCpuPkg.
