This patch updates "kvm_arm_exception_class" for these two EC, which the new EC will be parsed in kvm_exit trace events (for guest's usage of Pointer Authentication and Scalable Vector Extension). The same updates to "esr_class_str" for ESR_ELx_EC_PAC, by which we can get more accurate debug info. Trivial changes, update them in one go.
