UefiCpuPkg/SmmCpuFeaturesLib: Abstract PcdCpuMaxLogicalProcessorNumber

Browse Source 
REF:https://bugzilla.tianocore.org/show_bug.cgi?id=3218

Adds a new function called GetCpuMaxLogicalProcessorNumber() to
return the number of maximum CPU logical processors (currently
gUefiCpuPkgTokenSpaceGuid.PcdCpuMaxLogicalProcessorNumber).

This allows the the mechanism used to retrieve the CPU maximum
logical processor number to be abstracted from the logic that
needs the value.
