acpi/ghes, cper: Recognize and cache CXL Protocol errors

Add support in GHES to detect and process CXL CPER Protocol errors, as
defined in UEFI v2.10, section N.2.13.

Define struct cxl_cper_prot_err_work_data to cache CXL protocol error
information, including RAS capabilities and severity, for further
handling.

These cached CXL CPER records will later be processed by workqueues
within the CXL subsystem.
