UefiCpuPkg/PiSmmCpuDxeSmm: Remove dependence between APs
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2268
In current implementation, when check whether APs called by StartUpAllAPs
or StartUpThisAp, it checks the Tokens value used by other APs. Also the AP
will update the Token value for itself if its task finished. In this
case, the potential race condition issues happens for the tokens.
Because of this, system may trig ASSERT during cycling test.
This change enhance the code logic, add new attributes for the token to
remove the reference for the tokens belongs to other APs.
