The PEI flavor of CpuExceptionHandlerLib never populates more than 32 IDT vectors, and there is no CET shadow stack support in the PEI phase. So there is no need to use the generic ExceptionHandler NASM source, which carries a 256-entry template and CET support, and writes to its own .text section when built using XCODE, which is not permitted in the PEI phase. So let's switch to the reduced SEC/PEI version of this component, which is sufficient for PEI and doesn't suffer from the same issue.
