The series patches are to refine SMM CPU Sync flow. After the refinement, SmmCpuSyncLib is abstracted for any user to provide different SMM CPU Sync implementation.
Compared to V2, has following refinement & changes: 1. rename SMM_CPU_SYNC_CXT to SMM_CPU_SYNC_CONTEXT 2. rename SemBlock to SemBuffer, SemBlockPages to SemBufferSize 3. remove empty lines among the local variable declarations 4. add assert before if condition check 5. update the comments for SmmCpuSyncCheckOutCpu, SmmCpuSyncGetArrivedCpuCount and SmmCpuSyncLockDoor. 6. remove unnecessary cxt local variable declarations.
