UefiPayloadPkg: auto-generate SEC ProcessLibraryConstructorList() decl

Rely on AutoGen for declaring ProcessLibraryConstructorList().

Build-tested with:

  python UefiPayloadPkg/UniversalPayloadBuild.py -a X64 -b DEBUG -t GCC5

  python UefiPayloadPkg/UniversalPayloadBuild.py -a X64 -b DEBUG -f \
    -t GCC5

  build -a X64 -b DEBUG -p UefiPayloadPkg/UefiPayloadPkg.dsc -t GCC5 \
    -D BUILD_ARCH=X64
