Subject: Add SmmCpuPlatformHookLib IsLmceStatusCheckNeeded interface PR review 
request

Hi JieWen and Greg,

Could you please help to review PR https://github.com/tianocore/edk2/pull/6557?

This PR is to add a new interface for SmmCpuPlatformHookLib which can used to 
check whether the LMCE status check is required depending on platform 
requirements.
By default, 2 edk2 implementations (UefiCpuPkg/SmmCpuPlatformHookLibNull  and 
OvmfPkg/SmmCpuPlatformHookLibQemu ) returns TRUE indicating LMCE status check 
should be performed. Platform specific implementation could return FALSE if 
would like to skip the LMCE check due to any reason.

This new interface will be consumed by UefiCpuPkg/PiSmmCpuDxeSmm/MpService.c  
SmmWaitForApArrival(). However, the consumer part PR will be submitted later to 
avoid immediate downstream build error. 
https://github.com/tianocore/edk2/pull/6557  PR allow downstream to implement 
platform specific implementation, thus the transition will be smooth when 
downstream received the updated SmmWaitForApArrival().

Please let me know if you have any questions.

Regards,
Swee Aun
