REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2212
In binary model the same binary may have to support both
S3 enabled and disabled scenarios, however not all DXE
drivers linking PiDxeS3BootScriptLib can return error to
invoke library DESTRUCTOR for releasing resource.
To support this usage model below PCD is used to skip
S3BootScript functions when PCD set to FALSE:
gEfiMdeModulePkgTokenSpaceGuid.PcdAcpiS3Enable
Test: Verified on internal platform and S3BootScript
functions can be skipped by PCD during boot time.
