OvmfPkg/SmmCpuFeaturesLib: Check SmBase relocation supported or not 

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4337

This patch is to check SmBase relocation supported or not.
If gSmmBaseHobGuid found, means SmBase info has been relocated
and recorded in the SmBase array. ASSERT it's not supported in OVMF.
