Jiaxin Wu 69eb9ad4a1 UefiCpuPkg: Implements SmmCpuSyncLib library instance
Implements SmmCpuSyncLib Library instance. The instance refers the
existing SMM CPU driver (PiSmmCpuDxeSmm) sync implementation
and behavior:
1.Abstract Counter and Run semaphores into SmmCpuSyncCtx.
2.Abstract CPU arrival count operation to
SmmCpuSyncGetArrivedCpuCount(), SmmCpuSyncCheckInCpu(),
SmmCpuSyncCheckOutCpu(), SmmCpuSyncLockDoor().
Implementation is aligned with existing SMM CPU driver.
3. Abstract SMM CPU Sync flow to:
BSP: SmmCpuSyncReleaseOneAp  -->  AP: SmmCpuSyncWaitForBsp
BSP: SmmCpuSyncWaitForAPs    <--  AP: SmmCpuSyncReleaseBsp
Semaphores release & wait during sync flow is same as existing SMM
CPU driver.
4.Same operation to Counter and Run semaphores by leverage the atomic
compare exchange.
