[edk2-platforms][PATCH v4 10/41] IntelSiliconPkg: Add MM SPI FVB services

["Michael Kubacki" <mikuback@linux.microsoft.com>]

From: Michael Kubacki <michael.kubacki@microsoft.com>

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=3307

Adds a Traditional MM and Standalone MM SPI FVB Service driver to
IntelSiliconPkg. These drivers produce the firmware volume block
protocol for SPI flash devices compliant with the Intel Serial
Flash Interface Compatibility Specification.
