REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3962 Two SMM variables (mSmrrSupported & mSmmFeatureControlSupported) are global variables, they control whether the SMRR and SMM Feature Control MSR will be restored respectively. To avoid the TOCTOU, add PCD to control SMRR & SmmFeatureControl enable.
