Series is also available at:
https://github.com/hwu25/edk2/tree/mpinitlib_opt_v5

V5 changes:
A. For patch 2, address a typo to resolve enlarging the microcode patch
   information buffer too early when it is not full;
B. For patch 4, relocate the logic of storing detected microcode patch
   before the application of microcode patch.

V4 history:
A. For patch 2, keep the calling sequence of functions:
   MicrocodeDetect() and MtrrGetAllMtrrs() unchanged for BSP.
B. For patch 2, in function LoadMicrocodePatch(), add the missing logic
   that handles the Extended Signature Table of a microcode patch.


V3 history:
For patch 3, correct license information for newly added header file.

V2 history:
A. For patch 2, rename function parameters and variables to better reflect
   their usage;
B. For patch 2, remove unneeded check in LoadMicrocodePatchWorker();
C. For patch 3, rename a couple of fields in the HOB structure;
D. For patch 3, update the 'ProcessorSpecificPatchOffset' field to point
   to the microcode patch header instead of microcode patch data;
E. Add a new patch 5 to address an issue that certain fields in the
   CPU_MP_DATA structure cannot be passed from PEI phase to DXE phase;
F. Add a new patch 6 to remove the redundant microcode related fields in
   the CPU_MP_DATA structure.

V1 history:
This series will introduce a couple of optimizations to the MpInitLib with
regard to microcode:

A. Reduce the copy size when loading the microcode patches data from flash
   into memory;
B. Produce a HOB to contain microcode patches information for subsequent
   consumers of the microcode patches during the boot flow.

Uni-test done for the series:
A. System boot to OS/Shell successfully on a real platform;
B. Add debug message to verify the same microcode patch is applied to each
   processor before and after the series.
