REF:https://bugzilla.tianocore.org/show_bug.cgi?id=3479 Updates VariableRuntimeDxe, VariableSmm, and VariableStandaloneMm to acquire variable flash information from the Variable Flash Information library. Note: This introduces a dependency on VariableFlashInfoLib in these modules. Therefore, a platform building the variable modules must specify an instance of VariableFlashInfoLib in their platform build.

| #  Provides SMM variable service.
 | |
| #
 | |
| #  This module installs SMM variable protocol into SMM protocol database,
 | |
| #  which can be used by SMM driver, and installs SMM variable protocol
 | |
| #  into BS protocol database, which can be used to notify the SMM Runtime
 | |
| #  Dxe driver that the SMM variable service is ready.
 | |
| #  This module should be used with SMM Runtime DXE module together. The
 | |
| #  SMM Runtime DXE module would install variable arch protocol and variable
 | |
| #  write arch protocol based on SMM variable module.
 | |
| #
 | |
| #  Caution: This module requires additional review when modified.
 | |
| #  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
 | |
| #  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.
