MdeModulePkg/Core/DxeIplPeim: Enhance Code in DxeIplFindDxeCore FunctionHEADmaster

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.
