Jiewen Yao 31d060d94e UefiCpuPkg/MicrocodeUpdate: Add MP support.
Support the case that BSP and AP are using different Microcode.
The previous logic validates new MCU on BSP only.
The enhanced logic will validate MCU on every BSP and AP.
As long as one processor loads the MCU successfully, it will be updated.

Jiewen Yao 2ed658240c UefiCpuPkg/MicrocodeUpdate: enhance flash write logic
The patch updated MicrocodeWrite() to move the Microcode replacement logic
to a standalone function -  UpdateMicrocodeFlashRegion().
More detail description is added in UpdateMicrocodeFlashRegion()
to improve readability.

The Microcode information is collected in InitializeMicrocodeDescriptor(),
so that FmpGetImage() can get the info directly.
MicrocodeRead() is not needed any more.

Jiewen Yao 882668595c UefiCpuPkg/MicrocodeUpdate: Add MicrocodeUpdate component.
MicrocodeUpdate supports update Microcode region via UEFI FMP capsule.

MicrocodeUpdate SetImage() will perform the Microcode version,
ProcessorSignature/ProcessorFlag, and try to load microcode.
If and only if the Microcode is loaded successfully, and new Microcode
will be updated to system flash region.
