Jeff Fan 719ff8cf3e UefiCpuPkg/CpuMpPei: Dump message if microcode signature not matched
Verification microcode signature is one enhancement and not one requirement from
IA32 SDM. This update is just to dump debug message instead of ASSERT() if the
updated microcode signature does not match the loaded microcode signature.

Jeff Fan 4da1ebf3b3 UefiCpuPkg/CpuMpPei: Fix potential AP mwait wakeup issue
If ApLoopMode is set to ApInMwaitLoop, AP will be placed into C-State by mwait
instruction. BSP will wakeup AP by write start-up signal in monitor address.
However, AP maybe waken by SMI/NMI/MCE and other condition. On this case, AP
will check if BSP wants to wakeup itself really. If not, AP will continue to
execute mwait to C-State.

One potential issue: BSP may not recognize AP was wakeup from C-State by other
event and BSP still writes start-up signal to wakeup AP. But AP does not aware
it and still execute mwait instruction to C-State. So, AP cannot be wakeup on
this case.

This fix is let AP to clear start-up signal when it really is wakeup to execute
AP function. And BSP will write start-up signal till AP clears it.

Jeff Fan c87e41b445 UefiCpuPkg/CpuMpPei: Place APs in proper loop mode after AP execution
After AP function is executed, we will place AP in proper loop mode. Because AP
maybe waken up by SMI or other reasons. We need to read signature in monitor
buffer to check if APs is waken up by BSP. If it is not waken up by BSP, we will
continue to place them into proper loop mode.
