UefiCpuPkg/PiSmmCpuDxeSmm: Consume SmmCpuSyncLib

Browse Source 
There is the SmmCpuSyncLib Library class define the SMM CPU sync
flow, which is aligned with existing SMM CPU driver sync behavior.
This patch is to consume SmmCpuSyncLib instance directly.

With this change, SMM CPU Sync flow/logic can be customized
with different implementation no matter for any purpose, e.g.
performance tuning, handle specific register, etc.
