__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
OvmfPkg.

Refactor initialization of CPU features during S3 resume.
In addition, the macro ACPI_CPU_DATA_STRUCTURE_UPDATE is used to fix
incompatibility issue caused by ACPI_CPU_DATA structure update. It will
be removed after all the platform code uses new ACPI_CPU_DATA structure.

CpuS3DataDxe allocates the "RegisterTable" and "PreSmmInitRegisterTable"
arrays in ACPI_CPU_DATA just so every processor in the system can have its
own empty register table, matched by APIC ID. This has never been useful
in practice.
Given commit e992cc3f48 ("UefiCpuPkg PiSmmCpuDxeSmm: Reduce SMRAM
consumption in CpuS3.c", 2021-01-11), simply leave both
"AcpiCpuData->RegisterTable" and "AcpiCpuData->PreSmmInitRegisterTable"
initialized to the zero address. This simplifies the driver, and saves
both normal RAM (boot services data type memory) and -- in PiSmmCpuDxeSmm
-- SMRAM.
(This simplification backs out a good chunk of commit 1158fc8e2c
("OvmfPkg/CpuS3DataDxe: enable S3 resume after CPU hotplug", 2020-03-04).
But CpuS3DataDxe still differs between UefiCpuPkg and OvmfPkg, due to the
latter supporting CPU hotplug; thus, we can't remove OvmfPkg/CpuS3DataDxe
altogether.)

During normal boot, CpuS3DataDxe allocates
- an empty CPU_REGISTER_TABLE entry in the
"ACPI_CPU_DATA.PreSmmInitRegisterTable" array, and
- an empty CPU_REGISTER_TABLE entry in the "ACPI_CPU_DATA.RegisterTable"
array,
for every CPU whose APIC ID CpuS3DataDxe can learn.
Currently EFI_MP_SERVICES_PROTOCOL is used for both determining the number
of CPUs -- the protocol reports the present-at-boot CPU count --, and for
retrieving the APIC IDs of those CPUs.
Consequently, if a CPU is hot-plugged at OS runtime, then S3 resume
breaks. That's because PiSmmCpuDxeSmm will not find the hot-added CPU's
APIC ID associated with any CPU_REGISTER_TABLE object, in the SMRAM copies
of either of the "RegisterTable" and "PreSmmInitRegisterTable" arrays. The
failure to match the hot-added CPU's APIC ID trips the ASSERT() in
SetRegister() [UefiCpuPkg/PiSmmCpuDxeSmm/CpuS3.c].
If "PcdQ35SmramAtDefaultSmbase" is TRUE, then:
- prepare CPU_REGISTER_TABLE objects for all possible CPUs, not just the
present-at-boot CPUs (PlatformPei stored the possible CPU count to
"PcdCpuMaxLogicalProcessorNumber");
- use QEMU_CPUHP_CMD_GET_ARCH_ID for filling in the "InitialApicId" fields
of the CPU_REGISTER_TABLE objects.
This provides full APIC ID coverage for PiSmmCpuDxeSmm during S3 resume,
accommodating CPUs hot-added at OS runtime.

The @file comments in UefiCpuPkg/CpuS3DataDxe say,
[...] It also only supports the number of CPUs reported by the MP
Services Protocol, so this module does not support hot plug CPUs. This
module can be copied into a CPU specific package and customized if these
additional features are required. [...]
The driver is so small that the simplest way to extend it with hotplug
support is indeed to clone it at first. In this patch, customize the
driver only with the following no-op steps:
- Update copyright notices.
- Update INF_VERSION to the latest INF spec version (1.29).
- Update FILE_GUID.
- Drop the UNI files.
- Replace EFI_D_VERBOSE with DEBUG_VERBOSE, to appease "PatchCheck.py".
