V2 changes: 1. Enable new API for MpInitLibUp. 2. Remove useless parameter FailedCpuList. 3. Rename StartupAllAPsWorker to StartupAllCpusWorker.
V1 Changes: REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1973 CpuFeatures solution introduces a policy which write msr bases on scope info. With this policy enabled, for the msr which is package scope, CpuFeature PEIM driver boots hang. The reason for this failure is current CPU MP Ppi not supports start bsp and AP at the same time. This patch serial introduce new API named StartupAllCPUs. And it add new ppi namded Edkii Mp Services2 Ppi, include EFI MP Serivces PPI and this new API. With this new PPi, CPU features PEI solution can start all CPUs at the same time. Because this patch only add one new API, i did belew tests: 1. Test StartupAllCpus with timeout == 0 pass. 2. Test StartupAllCpus with timeout != 0 pass.
