v2:
(1) Per Michael Kinney's suggestion, update GetApLoopMode() not to check CPUID
on MONITOR/MWAIT support if PcdCpuApLoopMode is not set to ApMwaitLoop.
(2) Add PcdCpuApTargetCstate to specify the C-state for APs instead of the max
C-state.
v1:
Support 3 AP loop modes:
A: Place AP in the Hlt-Loop state.
B: Place AP in the Mwait-Loop state.
C: Place AP in the Run-Loop state.
