OvmfPkg/SmmCpuPlatformHookLibQemu: Define IsCpuSyncAlwaysNeeded
This patch is to implement default IsCpuSyncAlwaysNeeded definition
for SmmCpuPlatformHookLibQemu. 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.
