Hao Wu 2ecd829972 MdePkg/BaseLib: Add new AsmLfence API 
REF:https://bugzilla.tianocore.org/show_bug.cgi?id=1193

This commit will add a new BaseLib API AsmLfence(). This API will perform
a serializing operation on all load-from-memory instructions that were
issued prior to the call of this function. Please note that this API is
only available on IA-32 and x64.

The purpose of adding this API is to mitigate of the [CVE-2017-5753]
Bounds Check Bypass issue when untrusted data are being processed within
SMM. More details can be referred at the 'Bounds check bypass mitigation'
section at the below link:
