MdeModulePkg/Core/DxeIplPeim: Enhance Code in DxeIplFindDxeCore Function
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4653
In DxeIplFindDxeCore function, there exists different behavior between
Debug and Release built BIOS. This change is used to unify both of
the code flow and fix the potential overflow of "Instance" variable.
In this change,
[1] Move the ASSERT_EFI_ERROR (Status) in failure to find DxeCore
in any firmware volume condition.
[2] Break the while-loop when not found required DxeCore.
This would make the Instance variable not overflow in while-loop.
[3] Add the CpuDeadLoop () in the end of the function and do not
return since DxeCore is mandatory for the following booting
to hand-off the PEI phase to DXE phase.
[4] In case of the CpuDeadLoop () is de-assert by debugger,
return the NULL pointer.
