UefiCpuPkg/CpuDxe: StartupAllAPs in parallel mode
SetMemoryAttributes() will sync BSP's MTRRs settings to all APs by StartupAllAPs
service in serial mode. It may caused much performance impact if there are too
much processors in system. This update is to invoke StartupAllAps in parallel
mode. IA32 SDM does suggest to program MTRRs in parallel mode.
