Subject: [PATCH] UefiCpuPkg: SecCoreNative without ResetVector

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=3492

Currently SecCore.inf having the resetvector code under IA32. if the
user wants to use both SecCore and UefiCpuPkg ResetVector it's not
possible, since SecCore and ResetVector(VTF0.INF/ResetVector.inf)
are sharing the same GUID which is BFV. to overcome this issue we can
create the Duplicate version of the SecCore.inf as SecCoreNative.inf
which contains pure SecCore Native functionality without resetvector.
SecCoreNative.inf should have the Unique GUID so that it can be used
along with UefiCpuPkg ResetVector in there implementation.

+# The entry point function is _ModuleEntryPoint in PlatformSecLib.
+# The entry point function starts in 32bit protected mode or 64bit
+# mode depending on how resetvector is implemented, enables
+# temporary memory and calls into SecStartup().
