In preparation of providing a standalone MM based FTW driver, move
the existing SMM driver to the new MM services table, and factor out
some pieces that are specific to the traditional driver, mainly
related to the use of UEFI boot services, which are not accessible
to standalone MM drivers.

In preparation of providing a standalone MM based variable runtime
driver, move the existing SMM driver to the new MM services table,
and factor out some pieces that are specific to the traditional
driver, mainly related to the use of UEFI boot services, which are
not accessible to standalone MM drivers.

driver that will be able to execute in the context of standalone
MM.

+# This driver will have external input - variable data and communicate buffer in SMM mode.
+# This external input must be validated carefully to avoid security issues such as

+# The whole SMM authentication variable design relies on the integrity of flash part and SMM.
+# which is assumed to be protected by platform. All variable code and metadata in flash/SMM Memory
+# may not be modified without authorization. If platform fails to protect these resources,

Thank you Liming. I will go through all Star's comments, and fix up
the patches before pushing.
What about the Quark and Vlv2 changes? (adding MmServicesTableLib)

require an implementation that is based on standalone MM.

MdeModulePkg/Universal/DebugSupportDxe/DebugSupportDxe.inf does not
build for AARCH64 since it does not provide the needed PlDebugSupport.h
header. So move the module to a x86 only section.

For build testing coverage, add the newly introduced MM_STANDALONE
versions of the fault tolerant write (FTW) and variable runtime
driver to MdeModulePkg.dsc. Note that the resulting binaries will
not be able to run, since they rely on dummy implementations of
MemoryAllocationLib and HobLib.
