ACPI: APEI: EINJ: Add CXL error types

ACPI 6.5 added six new error types for CXL. See chapter 18
table 18.30.

Add strings for the new types so that Linux will list them in the
/sys/kernel/debug/apei/einj/available_error_types file.

It seems no other changes are needed. Linux already accepts
the CXL codes (on a BIOS that advertises them).
