Jeff Fan 8677a56af6 UefiCpuPkg/DxeMpLib: Place APs to suitable state on Legacy OS boot
Currently, DxeMpLib only places APs into specified c-state in Exit Boot Service
callback function for UEFI OS boot. We need to put APs into specified c-state
for legacy OS boot also.

Jeff Fan 86af2eb8b4 UefiCpuPkg/DxeMpLib: Rename MpInitExitBootServicesCallback()
Rename MpInitExitBootServicesCallback() to MpInitChangeApLoopCallback() because
it will not only be invoked on Exit Boot Service Event, but also will be invoked
on Legacy Ready To Boot Event.

Jeff Fan ffd6b0b1b6 UefiCpuPkg/DxeMpLib: Allocate below 4GB mem for AsmRelocateApLoopFunc
Current implementation just allocates reserve memory for AsmRelocateApLoopFunc.
It not be safe because APs will be placed into 32bit protected mode on long mode
DXE. This reserve memory must be located below 4GB memory.

This fix is to allocate < 4GB memory for AsmRelocateApLoopFunc.

Jeff Fan 14e8137c82 UefiCpuPkg/MpInitLib: Do not wakeup AP if only one processor supported
If MaxLogicalProcessorNumber is only 1, we needn't to wake up APs at all
and needn't to register callback functions.

It could improve boot performance on single supported system.

Jeff Fan 3ed4e502b5 UefiCpuPkg/MpInitLib: Don't allocate reset vector in Exit Boot Service
In Exit Boot Services callback function, we cannot use allocate memory services
because it may change the memory map that has been gotten by OS.

This fix is not to allocate reset vector buffer after SaveRestoreFlag is set to
TRUE in MpInitExitBootServicesCallback(). Instead AllocateResetVector() will use
the previous allocated buffer address and save the contents before copying reset
vector code. At the same time, FreeResetVector() will restore original contents
after if SaveRestoreFlag is TRUE.

Jeff Fan 4d3314f694 UefiCpuPkg/MpInitLib: Place APs in safe loop before hand-off to OS
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*
