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.
