UefiCpuPkg/MpInitLib: Add two instances PeiMpInitLib and DxeMpInitLib 

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:
  1. Rename MpInitLibSwitchBsp to MpInitLibSwitchBSP to match PI spec

This service executes a caller provided function on all enabled APs.
@param[in] Procedure A pointer to the function to be run on
enabled APs of the system. See type
EFI_AP_PROCEDURE.
@param[in] SingleThread If TRUE, then all the enabled APs execute
the function specified by Procedure one by
one, in ascending order of processor handle
number. If FALSE, then all the enabled APs
execute the function specified by Procedure
simultaneously.
@param[in] WaitEvent The event created by the caller with CreateEvent()
service. If it is NULL, then execute in
blocking mode. BSP waits until all APs finish
or TimeoutInMicroSeconds expires. If it's
not NULL, then execute in non-blocking mode.
BSP requests the function specified by
Procedure to be started on all the enabled
APs, and go on executing immediately. If
all return from Procedure, or TimeoutInMicroSeconds
expires, this event is signaled. The BSP
can use the CheckEvent() or WaitForEvent()
services to check the state of event. Type
EFI_EVENT is defined in CreateEvent() in
the Unified Extensible Firmware Interface
Specification.
@param[in] TimeoutInMicrosecsond Indicates the time limit in microseconds for
APs to return from Procedure, either for
blocking or non-blocking mode. Zero means
infinity. If the timeout expires before
all APs return from Procedure, then Procedure
on the failed APs is terminated. All enabled
APs are available for next function assigned
by MpInitLibStartupAllAPs() or
MPInitLibStartupThisAP().
If the timeout expires in blocking mode,
BSP returns EFI_TIMEOUT. If the timeout
expires in non-blocking mode, WaitEvent
is signaled with SignalEvent().
@param[in] ProcedureArgument The parameter passed into Procedure for
all APs.
@param[out] FailedCpuList If NULL, this parameter is ignored. Otherwise,
if all APs finish successfully, then its
content is set to NULL. If not all APs
finish before timeout expires, then its
content is set to address of the buffer
holding handle numbers of the failed APs.
The buffer is allocated by MP Initialization
library, and it's the caller's responsibility to
free the buffer with FreePool() service.
In blocking mode, it is ready for consumption
when the call returns. In non-blocking mode,
it is ready when WaitEvent is signaled. The
list of failed CPU is terminated by
END_OF_CPU_LIST.
@retval EFI_SUCCESS In blocking mode, all APs have finished before
the timeout expired.
