MdeModulePkg/DxeMain: Fix BSP interrupts reenabled in ExitBootServices

Within function CoreExitBootServices(), this commit will move the call
of:

MemoryProtectionExitBootServicesCallback();

before:

SaveAndSetDebugTimerInterrupt (FALSE);
and
gCpu->DisableInterrupt (gCpu);

The reason is that, within MemoryProtectionExitBootServicesCallback(),
APIs like RaiseTpl and RestoreTpl maybe called. An example will be:

DebugLib (using PeiDxeDebugLibReportStatusCode instance)
 |
 v
ReportStatusCodeLib (using DxeReportStatusCodeLib instance)
 |
 v
Raise/RestoreTpl

The call of Raise/RestoreTpl APIs will re-enable BSP interrupts. Hence,
this commit refine the calling sequence to ensure BSP interrupts before
leaving CoreExitBootServices().
