KVM: x86: Define AMD's #HV, #VC, and #SX exception vectors
Add {HV,CP,SX}_VECTOR definitions for AMD's Hypervisor Injection Exception,
VMM Communication Exception, and SVM Security Exception vectors, along with
human friendly formatting for trace_kvm_inj_exception().
Note, KVM is all but guaranteed to never observe or inject #SX, and #HV is
also unlikely to go unused. Add the architectural collateral mostly for
completeness, and on the off chance that hardware goes off the rails.
