UefiCpuPkg/MpInitLib: Collect processors' CPUID & Platform ID info
REF:https://bugzilla.tianocore.org/show_bug.cgi?id=2429
This commit will collect the CPUID and Platform ID information for each
processor within system. They will be stored in the CPU_AP_DATA structure.
These information will be used in the next commit to decide whether a
microcode patch will be loaded into memory.
