Kun Qin f463dbaded MdeModulePkg: VariableSmmRuntimeDxe: Added request unblock memory interface
This changes added usage of MmUnblockMemoryLib to explicitly request
runtime cache regions(and its indicators) to be accessible from MM
environment when PcdEnableVariableRuntimeCache is enabled. It will bring
in compatibility with architectures that supports full memory blockage
inside MM.

# Runtime DXE part corresponding to SMM authenticated variable module.
#
# This module installs variable arch protocol and variable write arch protocol to provide
# variable service. This module need work together with SMM authenticated variable module.
#
# Caution: This module requires additional review when modified.
# This driver will have external input - variable data.
# This external input must be validated carefully to avoid security issues such as
# buffer overflow or integer overflow.
# 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,
# the authentication service provided in this driver will be broken, and the behavior is undefined.
