[PATCH v2 1/4] UefiCpuPkg/SmmCpuFeaturesLib: Move multi-instance function decl to header

["Michael Kubacki" <mikuback@linux.microsoft.com>]

From: Michael Kubacki <michael.kubacki@microsoft.com>

FinishSmmCpuFeaturesInitializeProcessor() is a multi-instance
internal library function that is currently not declared in a
header file but embedded in "SmmCpuFeaturesLib.c".

This change cleans up the declaration moving it to a new header
file "CpuFeaturesLib.h" and removing the local declaration in
"SmmCpuFeaturesLib.c".
