UefiCpuPkg: Add new EDKII_PEI_MP_SERVICES2_PPI
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1973 Add definition for new EDKII_PEI_MP_SERVICES2_PPI. It includes all APIs existed in EFI_PEI_MP_SERVICES_PPI and add new API EDKII_PEI_MP_SERVICES_STARTUP_ALL_CPUS. Cc: Ray Ni <ray.ni@intel.com> Cc: Laszlo Ersek <lersek@redhat.com> Cc: Chandana Kumar <chandana.c.kumar@intel.com> Cc: Star Zeng <star.zeng@intel.com> Signed-off-by: Eric Dong <eric.dong@intel.com> Reviewed-by: Ray Ni <ray.ni@intel.com> Regression-tested-by: Laszlo Ersek <lersek@redhat.com>
