IntelFsp2Pkg: auto-generate SEC ProcessLibraryConstructorList() decl

Rely on AutoGen for declaring ProcessLibraryConstructorList().

Build-tested with:

  build -a X64 -b DEBUG -m IntelFsp2Pkg/FspSecCore/Fsp24SecCoreM.inf \
    -p IntelFsp2Pkg/IntelFsp2Pkg.dsc -t GCC5

  build -a X64 -b DEBUG -m IntelFsp2Pkg/FspSecCore/FspSecCoreM.inf \
    -p IntelFsp2Pkg/IntelFsp2Pkg.dsc -t GCC5
