UefiCpuPkg/MpInitLib: Get ApLoopMode and MointorFilter size
Firstly, get ApLoopMode from PcdCpuApLoopMode. If MonitorMwait feature is not
supported, update ApLoopMode to ApHltLoop. If MonitorMwait feature is supported,
get MointorFilter size by CPUID.[EAX=05H]:EBX.BIT0-15.
v5:
1. Add comment block for enum AP_LOOP_MODE.
