BZ# 4093: Abstract SmmCpuFeaturesLib for sharing common code
This change stripped away the code that can be
shared with other archs or vendors from Intel
implementation and put in to the common file,
leaves the Intel X86 implementation in the
IntelSmmCpuFeatureLib. Also updates the header
file and INF file.
