MdeModulePkg/Variable: Update to consume SpeculationBarrier
REF:https://bugzilla.tianocore.org/show_bug.cgi?id=1417
Since BaseLib API AsmLfence() is a x86 arch specific API and should be
avoided using in generic codes, this commit replaces the usage of
AsmLfence() with arch-generic API SpeculationBarrier().
Please note that speculation execution barriers are intended to be
asserted for SMM codes, hence, this commit still preserve an empty
implementation of the speculation execution barrier for the DXE codes.
