OvmfPkg/PlatformPei: Refactor MaxCpuCountInitialization 

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3863

MaxCpuCountInitialization is splitted into two:
 - PlatformMaxCpuCountInitialization is for PlatformInitLib
 - MaxCpuCountInitialization is for PlatformPei. It calls
   PlatformMaxCpuCountInitialization then sets PCDs.
