edk2-platforms: Pre-allocate UPD buffer before FspWrapper
Customers request to initialize/update UPD buffer outside IntelFsp2Wrapper
for better code sharing and maintenance. Use MinPlatform SiliconPolicPei
to initialize UPD buffer and pass to FspWrapper by PCD. A new library
instance introduced to add dependency to FspWrapper to ensure
dispatching ordering.
