ACPI: extlog: Trace CPER Non-standard Section Body

ghes_do_proc() has a catch-all for unknown or unhandled CPER formats
(UEFI v2.11 Appendix N 2.3), extlog_print() does not. This gap was
noticed by a RAS test that injected CXL protocol errors which were
notified to extlog_print() via the IOMCA (I/O Machine Check
Architecture) mechanism. Bring parity to the extlog_print() path by
including a similar log_non_standard_event().
