UefiCpuPkg/MpInitLib: Allocate and initialize memory of MP Data buffer

Browse Source 
v5:
  1. Add comment block for enum AP_INIT_STATE and structure CPU_AP_DATA.
  2. Add more comment for structure CPU_INFO_IN_HOB.
  3. Add more clarification in structure _CPU_MP_DATA for those fields
     pass from PEI to DXE.
