UefiCpuPkg/MpInitLib: Remove redundant microcode fields in CPU_MP_DATA

Previous commits have introduced below fields in structure CPU_AP_DATA:

  UINT32                         ProcessorSignature;
  UINT8                          PlatformId;
  UINT64                         MicrocodeEntryAddr;

which store the information of:

A. CPUID
B. Platform ID
C. Detected microcode patch entry address (including the microcode patch
   header)

for each processor within system.

Therefore, the below fields in structure CPU_MP_DATA:

  UINT32                         ProcessorSignature;
  UINT32                         ProcessorFlags;
  UINT64                         MicrocodeDataAddress;
  UINT32                         MicrocodeRevision;

which store the BSP's information of:

A. CPUID
B. Platform ID
C. The address and revision of detected microcode patch

are redundant and can be removed.
