Register Exit Boot Service callback function MpInitExitBootServicesCallback() to
place AP one safe loop before hand-off to OS.
Allocated one reserved memory and copy the AsmRellocateApLoop() code into it. It
could avoid the CPU Dxe driver (located in Boot Service data range) crashed
after Exit Boot Service event.
Place AP into the target Cx-State (specified by PcdCpuApTargetCstate) could save
power if Monitor-mwait feature supported.
In long mode, switch AP into protected mode could let AP not require page table
when executing this safe loop. Page Table (located in Boot Service data range)
may crashed after Exit Boot Service event.
v3:
1. Rename *RellocateAp* to *RelocateAp*

vector. After End of PEI event triggered, we need to restore original the buffer
contents to avoid crash the OS on S3 boot.
In DxeMpInitLib, allocate the memory under 1MB for AP reset vector.

Add two MP Initialize Library instances PeiMpInitLib.inf and DxeMpInitLib.inf
with NULL implementation.
One PeiMpInitLib.inf is consumed by PEI MP driver. Another DxeMpInitLib.inf is
consumed by DXE MP driver.
Place MpInitLibStartupAllAPs()/MpInitLibStartupThisAp()/MpInitLibSwitchBSP()/
MpInitLibEnableDisableAP() into PeiMpLib.c and DxeMpLib.c, because they have
the different implementations and will be updated in latter patches.
v5:
1. Add back PeiExceptionHandlerLib.inf in UefiCpuPkg.dsc. It is removed
incorrectly.
v4:
1. Return EFI_UNSUPPORTED instead of EFI_SUCCESS for NULL implementation of
all Functions.
2. Sync MpInitLibxxx functions header updating described in v4 part of Patch
#4.
v3:
