UefiCpuPkg/CpuMpPei: Add GetApLoopMode() to get AP loop mode
Add GetApLoopMode() that will get PCD PcdCpuApLoopMode firstly. If it is
ApInMwaitLoop, we will check if MONITOR/MWAIT feature supported by CPUID. If
MONITOR/MWAIT feature is not supported, force AP loop mode to ApInHltLoop.
GetApLoopMode() also return the largest line size required.
