ACPI: APEI: GHES: Add helper for CPER CXL protocol errors checks
Move the CPER CXL protocol errors validity check out of
cxl_cper_post_prot_err() to new cxl_cper_sec_prot_err_valid() and limit
the serial number check only to CXL agents that are CXL devices (UEFI
v2.10, Appendix N.2.13).
Export the new symbol for reuse by ELOG.
