UefiCpuPkg CpuCommonFeaturesLib: Enhance Ppin code
...
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=1961
Enhance Ppin code to enable and unlock for TRUE State,
and disable and lock for FALSE State.
Note: enable and lock could not be set both.
According to SDM, once Enable_PPIN is set, attempt to write
1 to LockOut will cause #GP, and writing 1 to LockOut is
permitted only if Enable_PPIN is clear.

UefiCpuPkg/CpuCommonFeaturesLib: Register MSR base on scope Info.
...
Because MSR has scope attribute, driver has no needs to set
MSR for all APs if MSR scope is core or package type. This patch
updates code to base on the MSR scope value to add MSR to the register
table.
