OvmfPkg: build CpuS3DataDxe for -D SMM_REQUIRE 

The PiSmmCpuDxeSmm driver from UefiCpuPkg depends on the ACPI_CPU_DATA
structure -- created by a platform- and CPU-specific driver -- in order to
support ACPI S3. The address of this structure is communicated through the
dynamic PCD PcdCpuS3DataAddress.

The "UefiCpuPkg/Include/AcpiCpuData.h" header file documents the fields of
this structure in detail.

The simple/generic "UefiCpuPkg/CpuS3DataDxe" driver creates and populates
the structure in a conformant way, and it co-operates well with
PiSmmCpuDxeSmm, for OVMF's purposes.
