This patch adds the IsCpuSyncAlwaysNeeded interface to the SmmCpuPlatformHookLib.
This interface will determine whether the first CPU Synchronization should be
executed unconditionally when a SMI occurs.
If the function returns true, it indicates that there is no need to check the
system configuration and status, and the first CPU Synchronization should be
executed unconditionally.
If the function returns false, it indicates that the first CPU Synchronization is
not executed unconditionally, and the decision to synchronize should be based on
the system configuration and status.

This patch is to add SmmCpuPlatformHookBeforeMmiHandler interface
in SmmCpuPlatformHookLib.
The new API can be used to perform the platform specific items
before executing MMI Handler. For example, Intel can leverage
this API to clear the pending SMI bit after all CPUs finish the
sync and before the MMI handlers. If so, the the redundant
SMI can be avoided after CPU exit from current SMI.

Add SmmCpuPlatformHookLib that provides platform specific functions
that are used to initialize SMM and process SMIs. A Null instance
of this library is provided that should work for most platforms.
